So now I'm just looking at my homework and apparently I need to simplify these for a final answer, "-/square. Aug 25 Alex from Warner. To simplify radicals, rather than looking for perfect squares or perfect cubes within a number or a variable the way it is shown in most books, I choose to do the problems a different way, and here is how. The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. Here are the steps required for Simplifying Radicals: Find the prime factorization of the number inside the radical. Click on the link to see some examples of Prime Factorization. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. If the index is 3 (a cube root), then you need three of a kind to move from inside the radical to outside the radical. Move each group of numbers or variables from inside the radical to outside the radical. If there are nor enough numbers or variables to make a group of two, three, or whatever is needed, then leave those numbers or variables inside the radical. Notice that each group of numbers or variables gets written once when they move outside the radical because they are now one group. Simplify the expressions both inside and outside the radical by multiplying. Multiply all numbers and variables inside the radical together.

The properties of exponents, which we've talked about earlier, tell us among other things that $$\begin xy \end^=x^y^$$ $$\begin \frac \end^=\frac $$ We also know that $$\sqrt[a]=x^$$ $$or$$ $$\sqrt=x^$$ If we combine these two things then we get the product property of radicals and the quotient property of radicals. These two properties tell us that the square root of a product equals the product of the square roots of the factors. $$\sqrt=\sqrt\cdot \sqrt$$ $$\sqrt=\frac$$ $$where\:\: x\geq 0,y\geq 0 $$ The answer can't be negative and x and y can't be negative since we then wouldn't get a real answer. In the same way we know that $$\sqrt=x\: \: where\: \: x\geq 0$$ These properties can be used to simplify radical expressions. A radical expression is said to be in its simplest form if there are no perfect square factors other than 1 in the radicand $$\sqrt=\sqrt\cdot \sqrt=\sqrt\cdot \sqrt=4\sqrt$$ no fractions in the radicand and $$\sqrt=\frac\cdot \sqrt=\fracx$$ no radicals appear in the denominator of a fraction. $$\sqrt=\frac=\frac$$ If the denominator is not a perfect square you can rationalize the denominator by multiplying the expression by an appropriate form of 1 e.g. $$\sqrt=\frac\cdot =\frac=\frac$$ Binomials like $$x\sqrt z\sqrt\: \: and\: \: x\sqrt-z\sqrt$$ are called conjugates to each other. The product of two conjugates is always a rational number which means that you can use conjugates to rationalize the denominator e.g.

Er, the question got a downvote because it has nothing to do with this forum. As for places to get help with homework, there's also math.stackexchange.com: you might not like them, though, as they prefer to give hints rather than complete solutions. But I see you posted your question in several other locations, and someone was kind enough to help you with it, even if you rather implausibly denied it was homework (but yet mysteriously had an immediate follow-up question which also looked like homework). I'd be kind of interested in knowing what story you have to explain the urgency, other than an imminent due date..

To simplify radicals, rather than looking for perfect squares or perfect cubes within a number or a variable the way it is shown in most books, I choose to do the problems a different way, and here is how. Here are the steps required for Simplifying Radicals. Lesson Summary: In this lesson, you'll learn how to simplify radical expressions in Algebra. A Radical expression is just an algebraic expression that involves one or more square roots or cube roots. We can simplify expressions that involve radicals by a simple set of rules that are described in this lesson. The easiest way to gain confidence with radical expressions in algebra is to see numerous example worked step-by-step. In this way the student an see why things are done, and can see that all of these problems are solved in a similar way.

Learn about expressions with rational exponents like x^2/3, about radical expressions like √2t^5, and about the relationship between these two forms of representation. Learn how to evaluate and simplify such expression. Just as the square root undoes squaring, so also the cube root undoes cubing, the fourth root undoes raising things to the fourth power, et cetera. To indicate some root other than a square root when writing, we use the same radical symbol as for the square root, but we insert a number into the front of the radical, writing the number small and tucking it into the "check mark" part of the radical symbol. This tucked-in number corresponds to the root that you're taking. For instance, relating cubing and cube-rooting, we have: ". On the other hand, we may be solving a plain old math exercise, something having no "practical" application. Then they would almost certainly want us to give the "exact" value, so we'd write our answer as being simply " To simplify a term containing a square root, we "take out" anything that is a "perfect square"; that is, we factor inside the radical symbol and then we take out in front of that symbol anything that has two copies of the same factor. On a side note, let me emphasize that "evaluating" an expression (to find its one value) and "solving" an equation (to find its one or more, or no, solutions) are two very different things. In the first case, we're simplifying to find the one defined value for an expression. In the second case, we're looking for any and all values what will make the original equation true.

Introduces the techniques used and concepts involved in solving radical equations. That's how the math is supposed to work. But if I try squaring the terms on the left-hand side of the original. Yes, this means that you can use your graphing calculator to help you check your work. When I was solving "x + 2 = 5" above. Before we can simplify radicals, we need to know some rules about them. These rules just follow on from what we learned in the first 2 sections in this chapter, Integral Exponents and Fractional Exponents. Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction. We met this idea in the last section, Fractional Exponents. Basically, finding the The second item means: "Find the square root of `9` (answer: `3`) then square it (answer `9`)". The 3rd item means: "Square `9` first (we get `81`) then find the square root of the result (answer `9`)". In general we could write all this using fractional exponents as follows: Notice I haven't included this part: `(sqrt(a))^2`. In this case, we would have the square root of a negative number, and that behaves quite differently, as you'll learn in the Complex Numbers chapter later.
