Question

Use radical notation to write the expression. Simplify if possible.
(- 125) 1/3

Answer 1

Explanation:

Be certain to use " ^ " to indicate exponentiation. I think you meant:

(-125)^(1/3) where -125 is the base and 1/3 is the exponent.

That "1/3" indicates a cute root. Note then that 125 is the cube of 5, so that

5^3 = 125.

Then, (-125)^(1/3) = -(5^3)^(1/3), or -5^1, or just -5.
