如何确定根号2的十分位和百分位的数字,谢谢!

根号2不是约等于1.414吗？怎么会有这样的问题！
我不太明白你说的十分位和百分位是什么意思，是小数点后面的位数吗？手工开根号？！

那可能就是十分位是0.4 百分位是0.01

(1.25+1.5)=1.375
1.375^2<2<1.5^2
1.375<√2<1.5

(1.375+1.5)/2=1.4375
1.375^2<2<1.4375^2
1.375<√2<1.4375

(1.375+1.4375)/2=1.40625
1.40625^2<2<1.4375^2
1.40625<√2<1.4375

(1.40625+1.4375)/2=1.421875
1.40625^2<2<1.421875^2
1.40625<√2<1.421875

(1.40625+1.421875)/2=1.4140625
1.4140625^2<2<1.421875^2
1.4140625<√2<1.421875

(1.4140625+1.421875)/2=1.41796875
1.4140625^2<2<1.41796875^2
1.4140625<√2<1.41796875。

(1.25+1.5)=1.375
1.375^2<2<1.5^2
1.375<√2<1.5

(1.375+1.5)/2=1.4375
1.375^2<2<1.4375^2
1.375<√2<1.4375

(1.375+1.4375)/2=1.40625
1.40625^2<2<1.4375^2
1.40625<√2<1.4375

(1.40625+1.4375)/2=1.421875
1.40625^2<2<1.421875^2
1.40625<√2<1.421875

(1.40625+1.421875)/2=1.4140625
1.4140625^2<2<1.421875^2
1.4140625<√2<1.421875

(1.4140625+1.421875)/2=1.41796875
1.4140625^2<2<1.41796875^2
1.4140625<√2<1.41796875
√2=1.41
祝学习进步！
