Simplify the following expression

Assume x>0

x^-5/4 * x^5/2

A) The answer can be written in the form x^a where
the exponent a is : ?

B) The answer can be written in the form 1/x^b where
the exponent b is : ?

*Note: enter the exponent as a reduced fraction or integer.

Hello, I want to help you.
See below, please.
x^-(5/4) * x^(5/2)
= x^(-5/4 + 5/2)
= x^(-5/4 + 10/4)
=x^(5/4)
So, a = 5/4
Hope this helps you. :)
