Question

Can x^(1/3) be written as 1/x^3?

Answer 1

yes

Answer 2

But it's positive, and I have to find the 0s of the solution. The equation is x^(1/3) = -5/2, and I'm stuck of how to find x.

Answer 3

it can't be written that way. x^(1/3) means the cube root of x

Answer 4

1/x^3 is completely different

Answer 5
