回答1:

64×64+32×64
=64×(64+32)
=64×96
=64×(100-4)
=64×100-64×4
=6400-256
=6144
对于这一个简便方法计算题,我们先用到了乘法分配律,公共因数64,就变成64×(64+32),算得64×96,在利用拆分数字的方法把96拆成100-4,再利用乘法分配律分开,就变成64×100-64×4=6400-256=6144。希望我的回答能够帮助到您,敬请采纳,谢谢!

解:64x64+32x64
=64x(64+32)
=64x96
=64x(100-4)
=6400-256

回答4:

64×64+32×64
=(64+32)×64
=(100-4)×64
=100×64-4×64
=6400-256
=6144

回答5:

原式=64*(64+32)
=64*(100–4)
=64*100–64*4
=6400–252
=6148
