解答
(-2m^2n^2)/(m^3n^2)
=-2/m;
如果本题有什么不明白可以追问,如果满意记得采纳
如果有其他问题请采纳本题后另发点击向我求助,答题不易,请谅解,谢谢.
祝学习进步能给个详细点的过程吗?这种题目就是直接约分;(-2m^2n^2)/(m^3n^2)(分子分母有公因式m²n²)=(-2m²n²÷(m²n²))/(m³n²÷(m²n²))=-2/m
推荐
若2m+n=25,m-2n=2,则(m+3n)2-(3m-n)2=_.
如果2m-3n=2,m+2n=14,那么m-5n+3=多少
2m-3n-m+2n
计算:(2m+3n)(m-2n)=_____________________
[(-3n)^2-(m^2-3n)^2]/(2m)^2
两数和为3,积为-10 求这两个数
