We do this by dividing their exponents by 2 :           2 = 2  At the end of this step the partly simplified SQRT looks like this:          2 â¢ sqrt (30x), Rules for simplifing variables which may be raised to a power:   (1) variables with no exponent stay inside the radical   (2) variables raised to power 1 or (-1) stay inside the radical   (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. 0.4 B. I have solved the problem in the above photo and also given the explanation why the given polynomial is not equal to â-2â. It means that it is not a real number you can't find it if you mean like that. Because of the fundamental theorem of algebra, you will always have two different square roots for a given number. If a radical is fully simplified, there is no factor of the radicand that can be written as a power greater than or equal to the index, there are no fractions under the radical sign, and there are no radicals in the denominator. For our last example, we will simplify a more complicated expression, $\dfrac{10{{b}^{2}}{{c}^{2}}}{c\sqrt[3]{8{{b}^{4}}}}$. For example, the following radical expressions still have a real number root since the indices 3 and 5 are odd numbers. To multiply \sqrt{5} and \sqrt{2}, multiply the numbers under the square root.
