若M＜3,则化简|M-3|等于

若M＜3,则化简|M-3|等于 3×m×m等于几3×m×m等于几3×m×m等于几3×m×m等于几 M/(M/5+M/3) 等于? 若m为正整数,3^2m*4^2m*36^m/72^2m等于 若M-3的绝对值等于0,则M等于 若|m-3|-4等于0,则m等于---------- m+3m+5m+...+2011m-2m-4m-...-2010m等于多少? 若m等于它的倒数,m^2/m-2除以m-3/m^2-3m的值为 m分之3等于 若3包含于m-1.3m.m的平方-1 则m等于? 若m^2+m-1=0,求m^3+2m^2+2008等于多少? 若m²+m-1=0 则,m³+2m²+3等于 3m等于m的平方,5m等于m的立方,m最小是多少? 若m等于-5a+3b,N等于2a-7b,则M+N等于【】,M-N等于【】 若m等于-5a+3b,N等于2a-7b,则M+N等于【】,M-N等于【】 (m+3m+5m+.+2009m)-(2m+4m+6m+.+2010m)等于多少请说明原因 m-3分之3-m 等于多少 1/m + 1/m+3 等于?
