0.45×[4.85÷﹙3.8÷1.9)+3.6-1.56×2.07]
=0.45*【4.85÷2+3.6-3.2292】
=0.45*【2.425+3.6-3.2292】
=0.45*2.7958
=1.25811

0.45×[4.85÷﹙3.8÷1.9)+3.6-1.56×2.07]
=0.45*【4.85÷2+3.6-3.2292】
=0.45*【2.425+3.6-3.2292】
=0.45*2.7958
=1.25811

望采纳~~

=0.45×(4.85÷2+3.6-3.2292)
=0.45×(2.425+3.6-3.2292)
=0.45×2.7958
=1.25811
