Question

Which expression is equivalent to x^-5/3

Answer 1

Answer:

c

Step-by-step explanation:

with a fractional exponent, the denominator becomes the root number. so we need a root of 3, which only b and c have.

between those two, b has no negative present whereas c does. since the original exponent was -5/3 we know our answer should have one.

thus c is our answer.
