2^3 × 3^4 × 5^5
= (2×5)^3 × 3^4 × 5^2
= 1ooo × 81 × 25
= 2025000
或
= (2×5)^5 ÷ 4 × 81
= 1ooooo × 81 ÷ 4
= 2o25000
= (2×5)^3 × 3^4 × 5^2
= 1ooo × 81 × 25
= 2025000
或
= (2×5)^5 ÷ 4 × 81
= 1ooooo × 81 ÷ 4
= 2o25000

先將3^4拆開成3^3 *3，
5^5拆開成5^3 *5^2，
以下：
=2^3 * (3^3 *3) *(5^3 *5^2)
=2^3 * 3^3 *5^3 *5^2*3=( 2*3*5 )^3 *3 *5^2=30^3 *(3 *25)=27000 * 75=2025000
5^5拆開成5^3 *5^2，
以下：
=2^3 * (3^3 *3) *(5^3 *5^2)
=2^3 * 3^3 *5^3 *5^2*3=( 2*3*5 )^3 *3 *5^2=30^3 *(3 *25)=27000 * 75=2025000

2x2x2=8 8x3x3x3x3=648 648x5x5x5x5x5=2025000
