thank you, Scott or whomever
simplify the square root if 108
ok.
I got 9x12
which then prime factorization = 2.2.3.3.3
then
i get it means the square root of 2.2.3.3.3
but then i get stuck
thank you

well you already have
sqrt( 2^2 * 3^2 * 3 )
= 2*3 * sqrt 3
= 6 sqrt 3
sqrt( 2^2 * 3^2 * 3 )
= 2*3 * sqrt 3
= 6 sqrt 3

well
sqrt (2^2) = sqrt 4 = 2
sqrt (3^2) = sqrt 9 = 3
sqrt 3 = sqrt 3
in general
sqrt (a^2 b^2) = a b
sqrt (2^2) = sqrt 4 = 2
sqrt (3^2) = sqrt 9 = 3
sqrt 3 = sqrt 3
in general
sqrt (a^2 b^2) = a b

remember sqrt 36 = 6
sqrt ( 6*6 ) = 6
sqrt (6^2) = 6
all the same written differently
sqrt ( 6*6 ) = 6
sqrt (6^2) = 6
all the same written differently
