Work Step by Step

We are given the expression $-3z^{4}\times10z^{7}$. First, we can group like terms. $(-3\times10)\times(z^{4}\times z^{7})$ Next, we can use the product rule, which holds that $a^{m}\times{a^{n}}=a^{m+n}$ (where a is a real number, and m and n are positive integers). $-30\times(z^{4+7})=-30z^{11}$
