Work Step by Step

We are given the expression $2x^{3}\times5x^{7}$. First, we can group like terms. $(2\times5)\times(x^{3}\times x^{7})$ 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). $10\times(x^{3+7})=10x^{10}$
