(2a^2)^3*[-ab^2+(-1/4a^2b^2)^2]+1/2(a^2b)^2
(2a^2)^3*[-ab^2+(-1/4a^2b^2)^2]+1/2(a^2b)^2

(2a^2)^3*[-ab^2+(-1/4a^2b^2)^2]+1/2(a^2b)^2
答:题目不会这样吧?没有化简的意思.
(2a^2)^3*[-ab^2+(-1/4a^2b^2)^2]+1/2(a^2b)^2
=(2a²)³×[-ab²+(-a²b²/4)²]+(a²b)²/2
=8(a^6)×(-ab²+(a^4)*(b^4)/16]+(a^4)b²/2
=-8(a^7)b²+(a^10)*(b^4)/2+(a^4)b²/2
