计算结果等于1884/5,等于376.8

-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

-3.14×35.2+6.23×(-23.3)-1.57×36 =-3.14×35.2-6.23×23.3-1.57×36 =-110.528-145.159-56.52 =-312.207

3.14x35.2+6.28x23.3+1.57x36.4 =3.14x35.2+3.14x46.6+3.14x18.2 =3.14x(35.2+46.6+18.2) =3.14x100 =314

=-3.14乘35.2-3.14乘46.6-3.14乘18.2 =-314

6!/3!x3!等于少 =(1*2*3*4*5*6)/(1*2*3*1*2*3) =(4*5*6)/(1*2*3) =20 6!/2!X2!X2! =(1*2*3*4*5*6)/(2*2*2) =1*3*5*6 =90 3.14x2x36等于多少 请详细描叙问题

1.1304

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
