Question:
Using square root table, find the square root
4192
Solution:
$\sqrt{4192}=\sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 131}$
$=2 \times 2 \sqrt{2} \times \sqrt{131}$
The square root of 131 is not listed in the table. Hence, we have to apply long division to find it.
Substituting the values:
$=2 \times 2 \times 11.4455 \quad$ (using the table to find $\sqrt{2}$ )
= 64.75
