Answer
$36a^{5}b^{10}$
Work Step by Step
We are given the expression $(-6a^{4}b)(2b^{3})(-3ab^{6})$. We can simplify by first grouping like terms.
$(-6\times2\times-3)\times(a^{4}\times a)\times(b\times b^{3}\times b^{6})$
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).
$36\times (a^{4+1})\times (b^{1+3+6})=36a^{5}b^{10}$
