50x125x16用简便方法计算

125x16 =125x(2x8) =(125X8)x2 =1000x2 =2000

125×16 =125×8×2 =1000×2 =2000

=329×125×8×2 =329×2×125×8 =658×1000 =658000

125X50x16 =125x50x8x2 =(125x8)x(50x2) =1000x100 =100000 行家正解,不明白可以追问!祝您学习进步 满意请点击下面的【选为满意回答】按钮,O(∩_∩)O谢谢

125x16x25 =(125×8)×(2×25) =1000×50 =50000

原式 =125x16x39 =(125x8)x(2x39) =1000x78 =78000

连乘最常用的简单算法就是凑零,也就是凑整百。 可以拆成125X4X250X4X4X6,=500X1000X24=5X24X100X1000 这样就好算了,记住一些乘出来可以凑成整百的就好。 25X4=100 125X4=500 125X8=1000 差不多就这些

对的 125*16=125*(8*2) 125*16=125*16

125×35×16 =125×35×4×4 =500×140 =70000

(125Ⅹ22十125)x16用简便方法计算 (125Ⅹ22十125)x16 =125*(22+1)*16 =125*8*(2*23) =46*1000 =46000
