初二上计算a^3(ab^2+b^3)^2÷(1/2ab)^2÷(a+b)^2
初二上计算a^3(ab^2+b^3)^2÷(1/2ab)^2÷(a+b)^2
初二上计算a^3(ab^2+b^3)^2÷(1/2ab)^2÷(a+b)^2
a^3(ab^2+b^3)^2÷(1/2ab)^2÷(a+b)^2
=4(a^4b^2+a^3b^3)÷(ab)^2÷(a+b)^2
=4(ab)^2(a^2+ab)÷(ab)^2÷(a+b)^2
=4(a^2+ab)÷(a+b)^2
=4a(a+b)÷(a+b)^2
=4a/(a+b)
4a/(a+b)
a^3(ab^2+b^3)^2÷(1/2ab)^2÷(a+b)^2
=a^3(ab^2+b^3)^2/[(1/2ab)^2(a+b)^2]
=a^3*{(ab^2+b^3)/[1/2ab(a+b)]}^2
=a^3*{b^2/[ab/2]}^2
=ab^2/1/4
=4ab^2
初二上计算a^3(ab^2+b^3)^2÷(1/2ab)^2÷(a+b)^2
(初二数学)化简2a-7ab+2b除以a+b+3ab
计算a^2b(ab^2-3ab)
计算(a-2b)(a^2-3ab+b^2)?
计算:2ab[(2ab)²-3b(ab+a²b)-ab²]
初二计算1题(SOS)!要有详细的解答过程!~~~1/a-1/b=3,则2a+3ab-2b/a+2ab-b=( )
初二因式分解8a^3b^2-12ab^3c+ab
几道初二因式分解计算1.已知a+b=2 ab=2 求1/2a^3+a^2b^2+1/2ab^32.利用分解因式证明25^7-5^12能被120整除
计算2A(A^2 -AB+B^2)-3AB(4A-2B)
计算3ab(2ab^2-ab-b^2)-6ab(a^2-2ab-b^2)
计算(3ab+a^2/a^2-b^2)/(a+3b/a-b)
计算:(a^2+3ab+b^2)(a^2-3ab+b^2)=
计算(3a^2b-7ab^2-a^2b^2)`5ab
计算(4a²b-3ab)+(-5a²b+2ab)
5ab×(2a-b+0.要需要分解因式,初二的教科书上有
计算(a^-3b^-2)^-2x(ab^3)^-3
计算2a^2×b^4-3(ab^2)^2
计算(2ab^2)乘以(-3a^2b)^2
