7.

 

P  =  d3/2

 

When  d  =  6.76, we have

 

P  =  (6.76)3/2    ≈  17.58

 

 

 

8.   Hard to read this...but I think we have

 

3√x3

____

5√x2

 

 

Writing  in exponential form, we have

 

x^(3/3)                                   a^m

_____              using            _____        =    a^(m - n)         we  have  

x^(2/5)                                   a^n 

 

 

x ^( 3/3  - 2/5)  =

 

x^(1 - 2/5)  =

 

x^(5/5 - 2/5)  =

 

x^(3/5)
