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