Question

Match the following square roots with their respective values.

• A. 19

• D. 16

Answer 1

$256=4\times 64=16\times 16$
$625=5\times 125=25\times 25$
$484=4\times 121=2\times 2\times 11\times 11=22\times 22$
$361=19\times 19$

$\therefore \sqrt{256}$ = 16,
$\sqrt{361}$ = 19,
$\sqrt{484}$ = 22,
$\sqrt{625}$ = 25.
