See the entire solution process below:

#### Explanation:

First, rewrite the expression as:

$\left(7.77 \times 9.76\right) \left({10}^{3} \times {10}^{9}\right) k g$ $m$

Next, multiply the terms within the parenthesis:

$75.8352 \times {10}^{3 + 9} k g$ $m = 75.8352 \times {10}^{12} k g$ $m$

Or

$7.58352 \times {10}^{13} k g$ $m$
