5^a + 5^a = ^1 =? (^ means "to the power of")
my book says 6(5^a).
I just don't see that though!
(and my book asks this question, but shows NO examples or explanations of a lone power without a base being added. Grr. I mean, what do I do with ^1? N do I assume that it has the same base as the rest of the equation?)
and I can't find other examples of adding two identical polynomials, really any polynomials, with exponents. Everything is all "don't do (3+4)^2 = 3^2 + 4^2. THIS, I do know. Sigh.
any help is much appreciated.
