(1.6m*1m)*2+(1.3m*1m)*2+1.6m*1.3m= 多少面积?

(1.6m*1m)*2+(1.3m*1m)*2+1.6m*1.3m= 多少面积?
(1.6m*1m)*2+(1.3m*1m)*2+1.6m*1.3m= 多少面积?

(1.6m*1m)*2+(1.3m*1m)*2+1.6m*1.3m= 多少面积?
(1.6m*1m)*2+(1.3m*1m)*2+1.6m*1.3m=6.33

???既然你写的这么详细还问多少面积什么意思呢 ？？？？7.88吧~~~ 我都不会算了呵呵

m*m-5m-1=0则2m*m-5m+1/m*m 已知m*m+m-1=0,求m*m*m+2m*m-2005 (1.6m*1m)*2+(1.3m*1m)*2+1.6m*1.3m= 多少面积? 计算M-M^2/M^2-1*M-1/M除以(M-1/M+1)^2 解方程 2m-m*m 1=2(m*m-2m)(m*m-2m) 已知m＞4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3| 因式分解m^2(m+1)-(m-1) m^2(m+1)-m-1 因式分解 化简|m|+|m-1|+|m-2| 化简:m+|(1+m^2-2m)/(m-1)| （m+1)(m+2)(m-1)(m-2)怎么计算? 解不等式m(m^-2m+1)/m+1 m(m+1)(m+2)(m+3)+1? 分式m-m^2分之m^2-2m+1 化简 |m|+| (2+m-m^2) 除以(m+1) | 化简 |m|+| (2+m-m^2) 除以(m+1) | 化简|6-m|-|2m+1|+|m+5| (m (1),(-m-n)(-m+n) (2),(-m+n)(m-n)
