Question

Find the radical equivalent of 27^2/3 and compute it.
please help i'm taking a test.

Answer 1

Explanation:

27^(2/3) = [cube root (27)]^2 = 3^2 = 9

Answer 2

Note that (a^b)^c=a^(bc) so in this case we have:

(27^(1/3))^2 the cube root of 27=±3

(±3)^2 and ±3^2=9

So the equivalent expression is 9 or if you need an exponent 9^1 :)

I am assuming that you meant 27^(2/3)
