Square roots are radical

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(9x2y10) ?

To solve this, it is good to factor under the radical ( or factor the square root)

So we get

sqrt(9x2y10)

=

(3xy5)
