解：原式=3.61×（10-0.1）+3.61×10
=3.61×（10-0.1+10）
=3.61×（20-0.1）
=3.61×20-3.61×0.1
=72.2-0.361
=71.839
=3.61×（10-0.1+10）
=3.61×（20-0.1）
=3.61×20-3.61×0.1
=72.2-0.361
=71.839

3.61×9.9+36.1
=3.61×9.9 + 3.61×10
=3.61×19.9
=3.61×（20-0.1）
=72.2-0.361
=71.839
=3.61×9.9 + 3.61×10
=3.61×19.9
=3.61×（20-0.1）
=72.2-0.361
=71.839
