Can anyone explain to me how to do the following:
4^17 - 4^14 ?

It appears the solution is something like 4^14(4^3-1). How do you arrive at this?

Thanks a bunch!

You need to know the rule for multiplying exponents with the same base

x^a*x^c = x^(a+c)

4^17 - 4^14 ==> 4^14*4^3 - 4^14 ==> 4^14(4^3 - 1)
