化简:【2m/(m+2) - m/(m-2)】÷m/(m²-4)
【2m/(m+2) - m/(m-2)】÷m/(m²-4)
=[2m(m-2)-m(m+2)]/(m²-4)× (m²-4)/m
=(2m²-4m-m²-2m)/m
=(m²-6m)/m
=m-6
化简m*m^2*m+m^2*m-m^2*m^2-m^3.
化简(m*m-2m)/(4-m*m)
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
(m^3-m)/(2m+2)化简
化简|m|+|m-1|+|m-2|
m(m-3)/2+m化简
化简 |m|+| (2+m-m^2) 除以(m+1) |
化简 |m|+| (2+m-m^2) 除以(m+1) |
化简:m+|(1+m^2-2m)/(m-1)|
已知m的绝对值=-m 化简|m|-|m-2|
化简|6-m|-|2m+1|+|m+5| (m
化简|m+2|+|m-3|
化简并求值 m*m*m-2m*m+m除以m*m*m-m 其中m=2011
化简:【2m/(m+2) - m/(m-2)】÷m/(m²-4)
化简:(2m/m+2-m/m-2)/ ( m/m²—4)=?
M^2-2M+1/M^2-1除以(M-1-M-1/M+1)化简
化简:(m/m+3-2m/m+3)÷m/m^-9
m^2+2m
