2×(-3) (-4)×括号1/6 1/4×(-3)等于多少

此题不完整:① (-3) (-4)之间缺运算符;② “括号”只有一半;③ 1/6 1/4之间缺运算符。 改为:2×(-3)×(-4)×(⅙×¼)×(-3) =-3

解答:6/5*(-1/3-1/2)*4/5 =6/5*(-5/6)*4/5 =-1*4/5 =-4/5

解: (1/6+3/4-2/3)*12 =1/6 *12+3/4 *12 -2/3 *12 =2+9-8 =11-8 =3

1/2+(5/6-3/4) =1/2+(10/12-9/12) =1/2+1/12 =7/12

(1/4+2/9)x3.6 =1/4x3.6+2/9x3.6 =0.9+0.8 =1.7 谢谢,请采纳

如图

-1^4+1/6×【2-(-3)^2】×(-1)^11 =-1+1/6×[-7]×(-1) =-1+7/6 =1/6。

=(-2/12+9/12-1/12)*(-48)=6/12*(-48)=1/2*(-48)=-24

一又1/24-2×括号3/8+1/6-3/4括回乘十二简便运算 一又1/24-2×括号3/8+1/6-3/4括回乘十二 =-25/24-2*(3/8+1/6-3/4)*12 =-25/24-24*3/8-24*1/6+24*3/4 =-25/24-9-4+18 =3又23/24
