Question
Using square root table, find the square root: $1312$
✓
Answer
Using the table to find $\sqrt{2}$ and $\sqrt{41}$
$\sqrt{1312}=\sqrt{2\times2\times2\times2\times2\times41}$
$=2\times2\sqrt{2}\times\sqrt{41}$
$=2\times2\times1.414\times6.4031$
$=36.222$
$\sqrt{1312}=\sqrt{2\times2\times2\times2\times2\times41}$
$=2\times2\sqrt{2}\times\sqrt{41}$
$=2\times2\times1.414\times6.4031$
$=36.222$
