Use the laws of exponents to simplify. Write the answer with positive exponents.
-$$z ^ { - 2 / 5 } \cdot z ^ { 3 / 5 }$$
A) $z ^ { 6 / 5 }$
B) $\mathrm { z } ^ { 1 / 5 }$
C) $z ^ { - 1 / 5 }$
D) $z ^ { 5 / 6 }$

Question

Quizplus · Accepted Answer

When multiplying powers with the same base, you add the exponents: $(-2/5) + (3/5) = 1/5$, so the answer is $z^{1/5}$.
