m/(m+1)+(1/m)【/1+(1/m)】等于多少m/(m+1)+(1/m)【/1+(1/m)】等于多少m/(m+1)+(1/m)【/1+(1/m)】等于多少就这样=M/(M+1)+(M+1)/M

m/(m+1) +(1/m)【/1+(1/m)】等于多少
m/(m+1) +(1/m)【/1+(1/m)】等于多少

m/(m+1) +(1/m)【/1+(1/m)】等于多少
就这样

=M/(M+1)+(M+1)/M2
=[M3+(M+1)2]/[M2(M+1)]
=1+(2M+1)/(M3+M2)
2,3为三次方,二次方

m/(m+1) +(1/m)【/1+(1/m)】=m/(m+1) +1/m+1/m^2=m*m^2/m^2(m+1)+m*(m+1)/m^2(m+1)+(m+1)/m^2(m+1)=(m^3+m^2+2m+1)/m^2(m+1)
