    well, the easiest part is multiplying (3)(-7) = -21 the next part is multiplying (a^2)(a^4). when we have the same base (a) we keep the base and add the exponents (a^2)(a^4) = a^(4+2) = ?

    So the answer would be =-21a^6?

    Question so when there is only 1 exponent next to the base and the other base does not have one, do we make the base that does not a 1 exponent so we can add or No?

    as an example... (a)(a^3) = (a^1)(a^3) = a^4

    when there is no exponent, you can always make the exponent 1
