3.14x36

竖式 3. 1 4 x 3 6 ______________ 1 8 8 4 9 4 2 ———————— 1 1 3. 0 4

-3.14x35.2+6.28x(-23.3)-1.57x36.4 =-3.14x35.2+3.14x(-46.6)-3.14x18.2 =-3.14x(35.2+46.6+18.2) =-3.14x100 =-314

计算结果等于1884/5,等于376.8

3.14×36+3.14×47+3.14×17 =3.14×(36+47+17) =3.14×100 =314 明白请采纳,有疑问请追问! 有新问题请求助,谢谢!

(3.14-1.4)x36 =36*1.74 =62.64 ‘没有简算,直接计算

3.14x=75.36-x 4.14X=75.36 x=24

提取公因数3.14,则原式变为 3.14X[-35.2+2X(-23.3)-0.5X36.4] =3.14X[-35.2-46.6-18.2] =3.14X(-100) =-314
