## Homework Statement

Find critical numbers of the function: F(x)=t^3/4 - 2t^1/4

Derivative I got: F'(x)=3/4 t^-1/4 - 1/2 t^-3/4

## Homework Equations

## The Attempt at a Solution

I have found the derivative and I understand I must pull out a t in order to find critical numbers, and run across this issue of manipulating fractional exponents too often. How do I go about this? Thankyou.
