25x37x4用简便方法汁算

(25x4)x37=100x37=3700

1.25x37x4 =(25x4)x37 =100x37 =3700 2.56x99+56 =56x99+56x1 =56x(99+1) =56x100 =5600 3.101x37 =(100+1)x37 =3700+37 =3737 4.35x15+35x10x6+35x25 =35x(15+60+25) =35x100 =3500 5.22x98+44 =22x98+22x2 =22x(98+2) =22x100 =2200 6.22x98+44 =22x98+22x2 =22x(98+2) =22x100 =2200

25x37x4=25x4x37=100x37=3700

25x37x(2x4)=25x4x2x37=200x37=7400

(25x37)x4=25x4x37=100x37=3700 希望能够帮到你,还望采纳谢谢!

解:25*45*4原式=25*4*45 =100*45 =4500.

25*17*4=(25*4)*17=100*17=1700

25x37x4=25*4*37=100*37=3700

27x25x4=27x(25x4)=27x100=2700 望采纳,谢谢

你那个是8的阶乘还是感叹号
