B. Evaluate the radical expression.
= -32

Same as A above.
-----------
B. Evaluate the radical expression
? (Simplify your answer. Type an integer or a fraction)
= -32 still

A. Write the expression (-8)^(5/3) in radical notation.
cbrt[-8]^5
-----------------------
B. Evaluate the radical expression.
Take the cube root to get (-2)^5
Raise to the 5th power to get -32
