Question
Using square root table, find the square root: $4192$
✓
Answer
$\sqrt{4192}=\sqrt{2\times2\times2\times2\times2\times131}$
$=2\times2\sqrt{2}\times\sqrt{131}$ The square root of $131$ is not listed in the table.
Hence, we have to apply long division to find it.
Substituting the values, $=2\times2\times11.4455$
$\big($Using the table to find $\sqrt{2}\big)$
$=64.75$
