Answer 2

`\boxed{part \: 1.} \\ \boxed{ \: ans = - 8a^(5) b ^(2)} \\ ........................................................\\ \\ \boxed{part \: 2.} \\ \boxed{ \: ans = (6x ^(3) )/(y ^(3)) } \: or \: ((6x)/(y) ) ^(3) \\ \\ ........................................................\\ \boxed{part \: 3.} \\ \: \boxed{ans =(8a^(6))/(27b^(3)) } \\ ........................................................ \\ \boxed{part \: 4.} \\ \\ \boxed{ \: ans = 6^(3)g^(15)h{}^( - 12) } \\ ........................................................`

Explanation:

`\boxed{part \: 1.} \\ ........................................................ \\ (2a ^(3) b ^( - 2))( - 4a^(2)b^(4)) \to \\ \boxed{ \: ans = - 8a^(5) b ^(2)} \\ ........................................................\\ \\ \boxed{part \: 2.} \\ ........................................................\: \\ (12x^(4)y^(2))/(2xy^(5)) \to \\ \boxed{ \: ans = (6x ^(3) )/(y ^(3)) }= ((6x)/(y) ) ^(3) \\ \\ ........................................................\\ \boxed{part \: 3.} \\ ........................................................\\ \: ( (2a^(2))/(3b) )^(3) \to \: \\ (2^(3)a^(6))/(3^(3)b^(3)) =(8a^(6))/(27b^(3)) \\ \boxed{ans =(8a^(6))/(27b^(3)) } \\ ........................................................\\ \boxed{part \: 4.} \\ ........................................................ \\ (6g^(5)h^( - 4))^(3) \to\\ \boxed{ \: ans = 6^(3)g^(15)h{}^( - 12) } \\ ........................................................`
