4×25×32×25用简便法
4×25×32×25
=(4×25)×8x(4×25)
=100x8x100
=80000
4×25×32×25
=(4×25)×8x(4×25)
=100x8x100
=80000

4×25×32×25用简便法
4x25x4x8x25=100x25x32=3200x25=3200x5x5=16000x5=80000
4x25x4x8x25=100x25x32=3200x25=3200x5x5=16000x5=80000
第3个回答 2022-11-06
4×25×32×25
=(4×25)×(8×4)×25
=(4×25)×(4×25)×8
=100×100×8
=10000×8
=80000
=(4×25)×(8×4)×25
=(4×25)×(4×25)×8
=100×100×8
=10000×8
=80000

解:此题运用分配律将32化为4x8，再运用结合律将化解的4同25相乘，最后按四则运算法则进行计算，计算过程
4x25ⅹ32ⅹ25
=4ⅹ25ⅹ4ⅹ8ⅹ25
=(4x25)ⅹ(4ⅹ25)x8
=100ⅹ100ⅹ8
=10000ⅹ8
=80000。本回答被网友采纳
