Question

A little confused in this two problems. Would really appreciate the help. Thank you.
Problem 1:
x^(2/5)x^(-3/5)
Problem 2:
a^(n/2)a^(-n/4)

Answer 1

Do you need problem 1 to be in the form of a^(n/2)a^(-n/4)

Answer 2

Not necessarily. I'm just trying to simplify problem one. Problem two is similar but its a completely different problem.

Answer 3

according to indices law both powers will add up each other

Answer 4

so the final answer is x^(-1/5)

Answer 5

I wasn't sure at the beginning whether I added or multiplied. So thank you!

Answer 6

your welcome :)
