4a-1/(a+1)(a-1)=m/(a+2)+n/(a-1),则m+n=4a-1/(a+1)(a-1)=m/(a+2)+n/(a-1),则m+n=4a-1/(a+1)(a-1)=m/(a+2)+n/
4a-1/(a+1)(a-1)=m/(a+2)+n/(a-1),则m+n=
4a-1/(a+1)(a-1)=m/(a+2)+n/(a-1),则m+n=
4a-1/(a+1)(a-1)=m/(a+2)+n/(a-1),则m+n=
因为4a-1/(a+2)(a-1)=m/(a+2) + n/(a-1),且m/(a+2) + n/(a-1)=m(a-1)+n(a+2)/(a+2)(a-1) 所以4a-1/(a+2)(a-1)=m(a-1)+n(a+2)/(a+2)(a-1) 所以4a-1=m(a-1)+n(a+2) =ma-m+na+2n =a(m+n)-(m-2n) 所以4=m+n 1=m-2n m=4-n代入得n=1 得m=3 m+n=4
a^m-1*a³-2a^m*a^4-3a²*a^m+2
因式分解:(-a)^m+a*(-a)^m-1
a*a+4a+1=0,且a*a*a*a+m*a*a+1/2a*a*a+ma*a+2a=3求m的值
已知a不等于0,m是正整数,下列各式中,错误的是a:a^-M=1/A^m B:A^-M=(1/A)^M C:A^-M=-A^M D:A^-M=(A^M)^-1
a^m+1×a^3-2a^m×a^4-3a^2×a^m+2,第一采用!
化简 a^m+1*a^3-2a^m*a^4-3a^2*a^m+2
a^m-1+a^m-a^m+1 因式分解
因式分解(1-a)m-a-1=?
M=a+1/(a-2) (2
4a-1/(a+1)(a-1)=m/(a+2)+n/(a-1),则m+n=
已知a^3*a^m*a^2m+1=a^25,求m的值
(4a-1)/[(a+2)(a-1)]=m/(a+2)+n/(a-1),求m,n的值
2a^(2m+3)(-a)^2/(-a)^(m-1)=-2(a^3)^(m-1)/a m为多少
(-a)^2m+1÷a^m
分解因式 a^m-a^(m+1)
已知a*a+4a+1=0,且(a*a*a*a-ma*a+1)/(2a*a*a+ma*a+2a)=3 求m的值拜托各位大神
【1】a+a=a×a a= [ ]【2】a×a=a÷a a=[ ]【3】a×a=a-a a=[ ] [4]a-a=a+a a=[ ]
2a^(m+1)+4a^(m)-2a^(m-1) m为正整数
