What is n^2 + n^5 ?
Simply write out the n's without the exponents and you have the answer. Or replace them with a small number like two or one.
a lot of n's
n^2 + n^5 is simplified as far as possible.It can be factored to be n^2(1 + n^3).
it is already simplified, unless u have a value for n
its already done
