Answer
$m^{14}$
Work Step by Step
We are given the expression $m\times m^{7}\times m^{6}$.
We can use the product rule to simplify, which holds that $a^{m}\times a^{n}=a^{m+n}$.
More generally, the product of any number of exponential expressions with a common base is the common base raised to a power equal to the sum of the exponents of the factors.
Therefore, $m\times m^{7}\times m^{6}=m^{1+7+6}=m^{14}$
