12(3a+5b)^12*(3a-5b)^4÷[3(3a+5b)^4*(3a-5b)]^3
12(3a+5b)^12*(3a-5b)^4÷[3(3a+5b)^4*(3a-5b)]^3
= 12(3a+5b)^12*(3a-5b)^4÷[3^3*(3a+5b)^(4*3)*(3a-5b)^3
= 12(3a+5b)^12*(3a-5b)^4÷[27*(3a+5b)^12*(3a-5b)^3]
= (12/27)*(3a+5b)^(12-12)*(3a-5b)^(4-3)
= (12/27)*(3a+5b)^0*(3a-5b)^1
= (4/9)*1*(3a-5b)
= (4/9)*(3a-5b)
