(a-b)^m+3(b-a)^2(a-b)^m
如果(a-b)^2-(b-a)^3=M·(1-b+a),那么M表示________________.
计算:(b-a)^5(a-b)^m+(a-b)^(m+3)(b-a)^2
计算:(a-b)^m+3(b-a)^2(a-b)^m(b-a)^5
若(2a+3b)·M=9b^2-4a^2,则M等于多少?A.-2a+3b B.2a-3b C.-2a-3b D.2a+3b 】
(a-b)^3m*(b-a)^2m÷(b-a)^5m
已知a^3m=3,b^3n=2,求(a^2m)3+(b^n)^3 - a^2m·b^n的值
若(a^m+1b^n+2)·(a^2n-1b^2m)=a^5b^3则m+n
计算:(a-b)^(m)*(a-b)^(2)*[2(b-a)]^3*[(b-a)^(5)]^(2)/(a-b)^(m).
计算(a-b)^m(a-b)[2(b-a)]^3[(b-a)^5]^2÷(a-b)^m=

若m^2-3m+2=(m+a)(m+b)则a= b=
a(m-n)^2+(n-m)^3 (2)a(a+b)(a-b)-a(a+b)^2
已知a^3m=3,b^3n=2,求(a^2m)^3+(b^n)^3-a^2m·b^n·a^4m·b^2n的值.
己知a^3m=,b^3n=2,求(a^2m)^3+(b^n)^3-a^2m·b^n·a^4m·b^2n的值
