Question
Using square root table, find the square root,
11.11
✓
Answer
We have,
$\sqrt{11}=3.317$ and $\sqrt{12}=3.464$
Their difference is 0.1474
Thus, for the difference of 1 (12 - 11), the difference in the value of the square roots is 0.1474
For the difference of 0.11, the difference in the values of the square roots is,
0.11 × 0.1474 = 0.0162
$\therefore\sqrt{11.11}=3.3166+0.0162=3.328\approx3.333$
