@Reganbaughman417 could you take the square root of a number?

anonymous · Answer

yes 3

mathlegend · Answer

Okay, so you know that the 3 came out of the radical. So based off of what we did earlier can you rewrite it?

anonymous · Answer

3√x

mathlegend · Answer

Is that "x" a multiplication symbol?

anonymous · Answer

no

mathlegend · Answer

Is it supposed to be 9x^2?

mathlegend · Answer

If it is then @Reganbaughman417 that makes the problem a bit different.

mathlegend · Answer

$$\sqrt{9x ^{2}}$$

mathlegend · Answer

Is that it? @Reganbaughman417

yes thank you

mathlegend · Answer

Okay, so first, you already told me that the 9 would come out as a 3 which is awesome!

mathlegend · Answer

Now, we call exponents that are even "perfect". What we do with the perfect exponents is take half of them. So half of 2 is 1. Also, when an exponent is perfect it also comes out of the radical.
