Question says that you are asked to find 91,321,972 x 0.007004. doing a quick estimate by rounding the numbers in scientific notation.

91,321,972 can be written in scientific notation as $= 9.1 \times 10^7$ because decimal moved 7 places to the left.

0.007004 can be written in scientific notation as $= 7.0 \times 10^{-3}$ because decimal moved 3 places to the right.

So to get and estimate of their let's multiply

$9.1 \times 10^7 * 7.0 \times 10^{-3}$

$= (9.1* 7.0) \times 10^{7-3}$

$= 63.7 \times 10^{4}$

= 637000

Hence final answer will be close to 637000.
