2^5 × 3^6 × 4^6
= 2^5 × 3^6 × (2^2)^6
= 2^5 × 3^6 × 2^12
= 2^17 × 3^6

(-5)^6 × 25^2/125
= (-5)^6 × (5^2)^2/5^3
= (-5)^6 × 5^4/5^3
= 5^(6+4-3)
= 5^7
= 78125

3^7 × 7^3 × 2/(42)^3
= 3^7 × 7^3 × 2/(2 × 3 × 7)^3
= 3^7 × 7^3 × 2/(2^3 × 3^3 × 7^3)
= 3^(7-3) × 7^(3-3) × 2^(1-3)
= 3^4 × 7^0 × 2^(-2)
= 3^4 × 1 × 1/2^2
= (3^4)/(2^2)
= 81/4
= 20 1/4

2^3 × 3^5 × 4^2/12^2
= 2^3 × 3^5 × (2^2)^2/(2^2 × 3)^2
= 2^3 × 3^5 × 2^4/(2^4 × 3^2)
= 2^(3+4-4) × 3^(5-2)
= 2^3 × 3^3
= 8 × 27
= 216
