It is true, taking the square root of an expression can also be called "The radical"
We will write square root as sqrt on this website, thus
sqrt(4) = 2
and
sqrt(9x^{2}y^{10}) ?
To solve this, it is good to factor under the radical ( or factor the square root)
So we get
sqrt(9x^{2}y^{10})
=
(3xy^{5})
