#### Answer

$10^4;
\\10^3;
\\10^2;
\\10;
\\1$

#### Work Step by Step

Note that:
$74716
\\= 70,000 + 4,000 + 700 + 10 + 6
\\=(7\times 10000) + (4\times 1000) + (7 \times 100) +(1 \times 10) + (6 \times 1)
\\=(7 \times 10^4) + (4 \times 10^3) + (7 \times 10^2) + (1 \times 10) + (6 \times 1)$
Thus, the missing expressions in the given statement (in order) are:
$10^4;
\\10^3;
\\10^2;
\\10;
\\1$
