0.9+0.98+0.997+0.99994=?(要有运算过程)
0.9+0.98+0.997+0.99994=?(要有运算过程)
0.9+0.98+0.997+0.99994=?(要有运算过程)
0.9+0.98+0.997+0.99994=1-0.1+1-0.02+1-0.003+1-0.00006=4-0.12306=3.87694
希望能帮到您,我用的是手机,收不到追问,如果有疑问请发短消息给我,或者求助也可以哈~
掰手指
4-0.12306
计算机不就行了- - 3.87694
(1-0.1)+(1-0.02)+(1-0.003)+(1-0.00006)
=(1+1+1+1)-(0.1+0.02+0.003+0.00006)
=4-0.12306
=3.87694
我是这样口算的0.9+0.98+0.997+0.99994=4-(0.1+0.02+0.003+0.00006)=4-0.12306=3.87694
4-(0.1+0.02+0.03+0.00006)
=4-0.12306
=3.87694
0.9+0.98+0.997+0.99994=(1-0.1)+(1-0.02)+(1-0.003)+(1-0.00006)=(1+1+1+1)-(0.1+0.02+0.003+0.00006)=4-0.12306=3.87694
(1-0.1)+(1-0.02)+(1-0.003)+(1-0.00006)
=(1+1+1+1)-(0.1+0.02+0.003+0.00006)
=4-0.12306
=3.87694
希望能帮到你
0.9+0.98+0.997+0.99994=? (要有运算过程)
0.9+0.98+0.997+0.99994=0.9+0.9+0.08+0.9+0.097+0.9+0.09994=3.6+0.27694=3.87694
(1-0.1)+(1-0.02)+(1-0.003)+(1-0.00006)=4-(0.1+0.02+0.003+0.00006)=4-0.12306=3.87694
0.9+0.98+0.997+0.9994
=1-0.1+1-0.02+1-0.003+1-0.0006
=4-0.1236
