3.6×10.2的简便脱式计算

=3.6*(10+0.2) =3.6*10+3.6*0.2 =36+072 =36.72

3.6x10.2=3.6x10+3.6x0.2=36+0.72=36.72 您好,答题不易 如有帮助请采纳,谢谢

3.6*10.2=3.6*(10+0.2)=36+0.72=36.72

3.6X(10+0.2)=3.6X10+3.6X0.2=36+0.72=36.72

(1)3.6*10.1,=3.6*(10+0.1),=3.6*10+3.6*0.1,=36+0.36,=36.36;(2)5.2*(4.7-1.9),=5.2*2.8,=14.56;(3)0.98+4.3*1.25,=0.98+5.375,=6.355.

你好:谷哥22为您解答:3.6*10.2=3.6*10+3.6*0.2=36+0.72=36.72望采纳,感谢!

(1)3.6*7.8+3.6*2.2=3.6*(7.8+2.2)=3.6*10=36;(2)10.1*5.4 =(10+0.1)*5.4 =10*5.4+0.1*5.4=54+0.54=54.54;(3)5.8*9.24-8.24*5.8=5.8*(9.24-8.24)=5.8*1=5.8;(4)2.5*8.9*0.

45.55-(6.82+15.55) 34.52-17.87-12.23 6.43-(1.4-0.57)23.75-8.64-3.46 17.83-9.5-7.83-0.5 5.38+88.2-2.38+1.827.38-5.34+2.62-4.66 21.63-(8.5+9.63) 7.5-2.45+7.5+2.450.9+0.99+0.999 5.09-(0.09+1.23) 9.36-(4.36-3.5)609-708+306-108+202-198+

3.6*0.99 =3.6*(1-0.01) =3.6-3.6*0.01 =3.6-0.036 =3.564.

18.2/0.2-3.6*5=18.2*5-3.6*5=91-18=73
