4192
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 $\sqrt{2}\big)$
$=64.75$
$=2\times2\sqrt{2}\times\sqrt{131}$
