整式乘法,若(2m+2n-1)(2m+2n+1)=63,求m+n
整式乘法,若(2m+2n-1)(2m+2n+1)=63,求m+n
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
已知:m*m=n+2,n*n=m+2.求m*m*m-2mn+n*n*n(m不等于n).
若2m-n/m+2n=5,求3(2m-n)/m+2n-m+2n/2m-n+3的值
m,n,(2m-1)/n,(2n-1)/m为正整数,m,n>=2.求m,n
(m+n)(m-n)-(1-2n)化简
已知:2m-5n=0 求下式的值 (1+n/m-m/m-n)/(1+n/m-m/m-n)
求集合M={m|m=2n-1,n属于N*,且m
求集合M={m|m=2n-1,n属于N*,且m
求集合M={m/m=2n-1,n属於n*,且M
已知|2m-n/m+2n|=3,求2(2m-n)/m+2n-2m-n/m+2n-3的值
(1)已知|2m-5|+(2m-5n+20)²=0,求(m-n)²-(2m+n)(n-m)
