Answer 1

这道数学题的解答步骤如下：
7.3×10.2-0.73-0.73
=7.3×10.2-7.3×0.1-7.3×0.1
=7.3×（10.2-0.1-0.1）
=7.3×10
=73

Answer 2

原式=7.3ⅹ10.2-7.3ⅹ0.1-7.3x0.1
=7.3ⅹ(10.2-0.1-0.1)
=7.3x10
=73

Answer 3

简便计算7.3×10.2-0.73-0.73=0.73×10×10.2-0.73-0.73=0.73×102-0.73-0.73=0.73×（102-1-1）=0.73×100=73

Answer 4

7.3x10.2-0.73-0.73
=7.3x10.2-0.73x2
【提取7.3】
=7.3x(10.2-0.1x2)
=7.3x10
=73

Answer 5

7.3×10.2-0.73-0.73=7.3×10.2-0.73×2=7.3×10.2-7.3×0.2=7.3×（10.2-0.2）=7.3×10=73
