Maths: surds
so i'm doing surds and this question is confusing me
simplify:
$\sqrt{108}$
now i know that i can simplify it to
$\sqrt{36 \: } \: \: \: \sqrt{3}$
and then simplify the 36 to 6 and the answer would be
$6 \sqrt{3}$
but when i tried doing it with different values
$\sqrt{9} \: \: \sqrt{12}$
and i simplify the 9 to a 3 and the 12 to
$\sqrt{4 } \: \: \sqrt{3}$
and i simplify the 4 to 2 i'm left with 3, 2 and square root 3 and i don't undertand how to get 6/3 from that
