Question

Which expression is equivalent to 3 sqrt 27x^18

Answer 1

Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).

We split up the radicand into perfect squares. Once we do, we take out the things that were squared:

`3\sqrt{27x^(18)} = 3√(3*3*3x^2x^2x^2x^2x^2x^2x^2x^2x^2x^2) = 3*3*xxxxxxxxx√(3)`

`=9x^9√(3)`
