Answer 1

25x（120+8）×125
=（25x120十25X8）X125
=（25×100+25X20十200）x125
=（2500+500+200）x125
=（3000+200）X125
=3000×125+200X125
=375000+25000
=400000

Answer 2

简便计算过程方法如下
解：25×128×125
=25×（64×2）×125
=25×（8×8×2）×125
=（25×8）×2×（8×125）
=200×2×1000
=400×1000
=400000

Answer 3

25x128x125 的简便运算如下：
=25x (64x2)x125
=25x(8x8x2)x125
=（25x8）x2x（8x125)
＝200x2x1000
＝400x1000
＝400000

Answer 4

=25*4*4*8*125
=(25*4)*4*(8*125)
=100*4*1000
=400000

Answer 5

=25*8*8*2*125
=25*4*8*8*125
