Answer 1

1.1×105-10.5=1.1×105-105×0.1=(1.1-0.1)×105=1×105=105

Answer 2

1.1×105-10.5简便计算＝1.1×（100+5）-10.5＝1.1×100+1.1×5-10.5＝110+5.5-10.5＝105

Answer 3

1.1x105-10.5
=11x10.5-10.5
=(11-1)x10.5
=10x10.5
=105

Answer 4

简便计算=1*105+0.1*105-10.5
=105+10.5-10.5
=105+0
=105

Answer 5

因为10.5等于105×0.1，所以原式＝1.1×105-105×0.1＝105（1.1-0.1）＝105×1＝105
