5(3a^2b-ab^2)-(ab^2+3a^2b)怎么化简5(3a^2b-ab^2)-(ab^2+3a^2b)怎么化简5(3a^2b-ab^2)-(ab^2+3a^2b)怎么化简5(3a^2b-ab
5(3a^2b-ab^2)-(ab^2+3a^2b)怎么化简
5(3a^2b-ab^2)-(ab^2+3a^2b)怎么化简
5(3a^2b-ab^2)-(ab^2+3a^2b)怎么化简
5(3a^2b-ab^2)-(ab^2+3a^2b)
=15a^2b-5ab^2-ab^2-3a^2b
=(15-3)a^2b-(5+1)ab^2
=12a^2b-6ab^2.
=6ab*(2a-b)
把括号去掉.
原式=15a^2b-5ab^2-ab^2-3a^2b
=12a^2b-6ab^2
5(3a^2b-ab^2)-(ab^2+3a^2b)
=15a^2b-5ab^2-ab^2-3a^2b
=(15-3)a^2b-(5+1)ab^2
=12a^2b-6ab^2
=6(2a^2b-ab^2)
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
-ab(a^2b^5-ab^3-b)
合并同类项5a²b-3ab-4ab²+7ab-2ab²
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
5ab^2-{2a^b-[3ab^2-(4ab^2-2a^2b)]}
2ab(5ab^2+3a^2b)急要
-5a^2b^3+20ab^2-5ab
因式分解:(ab^2)^2×(-a^3b)^3×(-5ab)
2ab*(5ab²+3a²b)
已知ab^2=-2,求-ab(a^2b^5-ab^3-b)的值
化简求值-ab*(a^2b^5-ab^3-b),其中ab^2=-2
-ab(a^2b^5-ab^3-b),其中ab^2=-2
ab^2=一3,则-ab(a^2乘b^5-ab^3-b)=?
已知ab^2=-3,则-ab(a^2b^5-ab^3-b)=?
ab^2=3 求-ab(a^2b^5-ab^3-b)值
已知ab^2=6,求ab(a^2b^5-ab^3-b)的值
已知ab^2=-6,求-ab(a^2b^5-ab^3-b)的值
