$70329= (7 \times 10^4) + (0 \times 10^3) + (3 \times 10^2) + (2 \times 10) + (9\times 1)$
Writing the given number in its expanded form gives: $70329 \\= 70000+ 300 + 20+9 \\=(7 \times 10000) + (0 \times 1000) + (3 \times 100) + (2 \times 10) +(9\times 1) \\= (7 \times 10^4) + (0 \times 10^3) + (3 \times 10^2) + (2 \times 10) + (9\times 1)$
