how do you prove that the derivative of x^n is nx^n-1

I need help to find the proof

Prove by contradiction: If an integer n has the form 3K+1, then it does not have the form 9L+5.

I have a lot of trouble with proofs and need help.

If all the primes where (2,3,5) then you can multiply them together to get 30, but then you add 1. Like how 64 is made up of 2x2x2x2x2x2, which can't this new number be made up of multiple smaller...

Find an example of a set A and functions f :A→A and g:A→A such that f◦g=idA but g ◦ f does not equal idA. I am not sure what idA means or an example for this

I can't figure out how to prove that statement. Any help would be great.
