To simplify a square root: make the number inside the square root as small as possible (but still a whole number):Example: √12 is simpler as 2√3 Get your calculator and check if you want: they are both the same value!Here is the rule: when a and b are not negative...
For any number {eq}x \geq 0 {/eq}, the square root of {eq}x {/eq} is a nonnegative number {eq}\sqrt{x} {/eq} such that: {eq}\sqrt{x}^2 = x {/eq} It follows immediately that {eq}\sqrt{x^2} = x {/eq} An important vocabulary note: roots are often called radicals....
A General Note: The Product Rule for Simplifying Square Roots If aa and bb are nonnegative, the square root of the product abab is equal to the product of the square roots of aa and bb. ab=a⋅b√ab=√a⋅√b How To: Given a square ...
When numbers are not perfect squares, their square roots can be challenging, however, it is possible to simplify square roots to make the square roots easier to see and use. Dive into ways the rules of mathematics are used to define perfect and imperfect squares and learn how to evaluate ...

The number under the root must be a non-negative integer. We're aware that radicals of odd order also apply to negative numbers and that rational numbers have roots as well, but, for simplicity, we limit ourselves to the non-negative integer case. Of course, taking the root is not alway...

Because when you square a number, you will always get a positive result, so the principal square root of (b2)2(b2)2 will always be non-negative. One tip for knowing when to apply the absolute value after simplifying any even indexed root is to look at the final exponent on your ...
