Question 23630
{{{(9x^-12y^6)*(-4x^1y^7)}}}


When you multiply with the same base number, you multiply the coefficients and you add the exponents.

{{{-36 *(x^-11) *(y^13) }}}


However, negative exponents are NOT allowed.  To eliminate the negative exponents, remember that {{{x^-11 = 1/(x^11)}}}.

{{{-36*(1/(x^11))*y^13}}}


{{{(-36y^13)/ (x^11)}}}
