题型:数学计算
解:
-0.001*0.04402^3+0.418*0.04402^2-8.341*0.04402+220.9
=-0.001*0.000085300212808+0.418*0.04402^2-8.341*0.04402+220.9
=-0.001*0.000085300212808+0.418*0.0019377604-8.341*0.04402+220.9
=-0+0.418*0.0019377604-8.341*0.04402+220.9
=-0+0.00081-8.341*0.04402+220.9
=-0+0.00081-0.367171+220.9
=0.00081-0.367171+220.9
=-0.366361+220.9
=220.533639 答案:-0.001*0.04402^3+0.418*0.04402^2-8.341*0.04402+220.9=220.533639你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
