125x48 5x31简便运算

简便计算过程方法如下解:125x48x5x31=125x8x6x5x31=(125x8)x(6x5)x31=1000x30x31=930000

128*48=125*8*6=1000*6=6000望采纳,谢谢

=125x(32+48)=125x80=10000

125x48=125*8*6拆数,找因数8;48=8*6=1000*6利用125*8=1000=6000

125*48=125*8x6=1000*6=6000

125*48=125*8*6=1000*6=6000 望采纳

125x48的简便计算=125*8*6=1000*6=6000

125x48乘以50 =125*8*3*2*50 =1000*3*100 =300000

计算过程方法如下 解:125x125=120x125+5x125=15x8x125+625=15x1000+625=1500+625=15625

125x25x48=(5x25)x25x(4x4x3)=(25x4)x(25x4)x(3x5)=100x100x15=150000
