How do you write a surd as an exponential with a different base? How do you get from √128 to 2^(7/2)?

Hello! 
The question in my textbook asks me to find m when √128 = 2^m
 
I used an app to solve the question and writing “√128 as an exponential with a base of 2“ was one of the steps
Please help me understand how to get to 2^(7/2)! 
 
Thank you in advance!
