Answer 1

简便计算如下：谨悔袜
解：0.125x9.62x80x96.2
＝1/前者8x80x96.2/10x96.2
＝96.2x96.2
＝96.2＾2
＝（96+0.2）＾2
＝96＾2＋2x96x0.2+0.2＾祥激2
＝9216+192x0.2+0.04
＝9216+38.4+0.04
＝9254.4+0.04
＝9254.44

Answer 2

0.125×9.62×80×96.2
=(0.125×80)×9.62×96.2
=10×9.62×96.2
=96.2×96.2
=（100-4+0.2）×96.2
=100×96.2-4×96.2+0.2×96.2
=9620-384.8+19.24
=9254.44

Answer 3

这判铅里可以这样进行简便计算，先用0.125乘掘厅好以80等于10，然后再乘以9.62乘以96.2，这样只是达到了一定的简便计算，最后两个数相乘还是比较麻烦伏慧的。

原雀滑式=0.125×80×9.62×96.2
=10×9.62×96.2
=96.2×96.2
=9254.44
0.125×9.62×80×96.2=9254.44

Answer 5

0.125×9.62×80×96.2
=10×9.62×96.2
=96.2²租吵蔽弊州碰神
=(100-3.8)²
=100²-2×100×3.8+3.8²
=10000-760+14.44
=9240+14.44
