计算:(1)(-a^2)^3*a^3+(-4a)^2*a^7-5(a^3)^3 (2)(a-2b)^3*(2b-a)^4/(a-2b)^6

计算:(1)(-a^2)^3*a^3+(-4a)^2*a^7-5(a^3)^3 (2)(a-2b)^3*(2b-a)^4/(a-2b)^6
计算:(1)(-a^2)^3*a^3+(-4a)^2*a^7-5(a^3)^3 (2)(a-2b)^3*(2b-a)^4/(a-2b)^6

计算:(1)(-a^2)^3*a^3+(-4a)^2*a^7-5(a^3)^3 (2)(a-2b)^3*(2b-a)^4/(a-2b)^6
(1)(-a^2)^3*a^3+(-4a)^2*a^7-5(a^3)^3
=-a^6*a^3+16a^2*a^7-5a^9
=-a^9+16a^9-5a^9
=10a^9
(2)(a-2b)^3*(2b-a)^4/(a-2b)^6
=(a-2b)^3*(a-2b)^4/(a-2b)^6
=(a-2b)^(3+4-6)
=a-2b
