3.6×9.9+0.36简便计算

3.6*9.9+0.36=3.6*9.9+3.6X0.1=3.6X(9.9+0.1)=3.6X10=36

应该是气态h2s、so2等含硫的化合物.硫元素是土壤有机质的重要组分,一般是在蛋白质中,随动植物残体进入土壤有机质,燃烧时氧化,释放出带有刺激性气味的含硫气体.

3.6*9.9+0.36=0.36*99+0.36 =0.36*(99+1) =0.36*100 =36

0.36*3.6*9.9=1.296*(10-0.1)=1.296*10-1.296*0.1=12.96-0.1296=12.8496

=3.6*9.9+0.36+0.005 =3.6*9.9+3.6*0.1+0.005 =3.6*(9.9+0.1)+0.005 =3.6*10+0.005 =36+0.005 =36.005

3.6*9.9-0.36=3.6(9.9-10)=-0.36

9.9*3.6 =(10-0.1)*3.6 =10*3.6-0.1*3.6 =36-3.6 =32.4 如果我的答案对您有帮助,请点击下面的“采纳答案”按钮,送咱一朵小 红花鼓励下吧!祝您生活愉快!谢谢!麻烦采纳,谢谢!

3.6*9.9=3.6*10-3.6*0.1=36-0.36=35.64

3.6*9.9+3.6=3.6*(9.9+1)=3.6*10.9=39.24你好,本题已解答如满意,请点采纳

3.6*9.9+3.6=3.6*10-3.6*0.1+3.6=36-0.36+3.6=35.64+3.6=39.24再一种方法就是用竖式计算
