Question

Which of the following is the approximated value of $\sqrt{2}$?

• A. 1.1142.................
• B. 1.5142.................
• C. 1.4142.................
• D. 1.2142.................

Answer 1

The correct option is C

1.4142.................

Three of the approximated values of $\sqrt{2}$ are:

1.414,1.4142 and 1.41421

Since can have an infinite number of digits after the decimal point we cannot have an exact value for $\sqrt{2}$

So, we write as $\sqrt{2}$ =1.4142.................
