Question

Simplify square root of 1008 ( V` Represents the square root sign.)

Answer 1

So first factor it
1008=2*2*2*2*3*3*7
group them in similar pairs
1008=(2*2)(2*2)(3*3)*7
now remember we can do
$\sqrt{xy}= \sqrt{x} \sqrt{y}$ so
$\sqrt{1008}= (\sqrt{2*2}) (\sqrt{2*2}) (\sqrt{3*3}) (\sqrt{7})$=
2*2*3*$\sqrt{7}$=
12√7

the answer is B
