\(n^5 / n^3 = n^2\)

 

Is this what you are asking?  Laws of indices,  when you divide you subtract the index of the denominator from the index of

the numerator.                 5-3  =2 

 

In general

 

X^n   - X^m   = X^(n-m)

Hi Fras,

Welcome to the forum :)

Yes I know you have been here for a few weeks, that is still fairy recent though.

I like this answer :)

On the line X^n-X^m=X^(n-m)

 

I know you meant to write X^n/X^m=x^(n-m), but otherwise, yeah, good answer.
