Question

Find the square root of $3$ correct to two places of decimal

Answer 1

Since we need the answer correct to two places of decimal, we shall first find the square root up to three places of decimal. For this purpose we must add $6$ ( that is three pairs of ) zeros to the right of the decimal point.
$\therefore \sqrt{3}=1.732$ up to three places of decimal.
$\sqrt{3}=1.73$ correct to two places of decimal.
