快啊,今晚就要的!
(2a^m+2a^m-2*b^n-2+3b^n)*(3a^n+2*b^n+2)的值快啊,今晚就要的!
(a^m b^n-2)*(-2a^m-2b^n-2)^2*(3a^m 3b^n-2)^3*(1/2b^n-2 1/2a^m)^4 =(a^m b^n-2)*(-2)^2*(a^m b^n-2)^2*3^
(a-b)(m-2n)+(b-a)(2m-n)
计算-(m^a*n^b)^2*(m^2*n)^3
(A+B)(M-2N)
化简(a^m+b^n)(a^2m+b^2n)(a^m-b^n)
(-a^m-1b^n-2+3a^m+1b^n)/(-2a^m-2b^n-2)
1/27a^(3m-m) -1/3a^(m-n)*b^2n因式分解
a(m-n)^2+(n-m)^3 (2)a(a+b)(a-b)-a(a+b)^2
2a(m-n)与3b(n-m)的公因式是是m-n或n-m吗
(a-n)^2n-(b-m)^4m
(a-b)^m*(a-b)^n*(b-a)^2n*(b-a)^2m+1(m
为正整数)
2m(a-b)-3n(b-a)
2m(a-b)-3n(b+a)因式分解
2m(a-b)+3n(b-a)怎么作
若m等于-5a+3b,N等于2a-7b,则M+N等于【】,M-N等于【】
若m等于-5a+3b,N等于2a-7b,则M+N等于【】,M-N等于【】
若(m+n)^2-mn(m+n)=(m+n)·M,则M是() A.m^2+n^2 B.m^2-mn+n^2 C.m^2-3mn+n^2 D.m^2+mn+n^2
因式分解:a^(2m+3n)+a^(2m+3n-2)b^2-a^(2m+n)-a^(2m+n-2)b^2+a^(2m-2)b^2+a^2m
因式分解:a^(2m+3n)+a^(2m+3n-2)b^2-a^(2m+n)-a^(2m+n-2)b^2+a^(2m-2)b^2+a^2m
