Question

你能用简便方法计算下面各题吗48×125×9x87×125×32×25什么比较好算？

Answer 1

=6×(8×125)×9×87×(125×8)×(4×25)
=1000×1000×100×6×9×87
=100000000×54×87
=100000000×(50+4)×87
=100000000×(4350+348)
=100000000×4698
=469800000000

Answer 2

利用125x8＝1000，25x4＝100来计算
原式＝6x（8x125）x9x87x（125x8）x（4x25）
＝6x9x87x1000x1000x100
＝467800000000

Answer 3

48×125×9x87×125×32×25
=6×8×125×9x87×125×8×4×25
=87×6×9×8×125×125×8×4×25
=87×6×9×1000×1000×100
=469800000000

Answer 4

=6*（8*125）*9*87*（125*8）*（4*25）
=6*1000*9*87*1000*100
=469800000000
