计算: (a+b)^2(a-b)^2数学计算计算:(a+b)^2(a-b)^2：(a+b)^2(a-b)^2 =[(a+b)(a-b)]^2 =[(a^2)-(b^2)]^2 =a^4?

(a+b)^2(a-b)^2 =[(a+b)(a-b)]^2 =[(a^2)-(b^2)]^2 =a^4-2(a^2)(b^2)+b^4

(a+b)^2(a-b)^2 =(a^2-b^2)^2=a^4-2a^2b^2+b^4

(a+b)^2(a-b)^2 =[(a+b)(a-b)]^2 =[(a^2)-(b^2)]^2 =a^4-2(a^2)(b^2)+b^4

(a+b)^2(a-b)^2 =(a^2-b^2)^2=a^4-2a^2b^2+b^4

a^4-2a^2b^2+b^2
