Begin by multiplying the expressions inside the radicals. To rationalize a monomial denominator, we multiply the numerator and denominator by a radical that will eliminate the radical in the denominator.
sqrt(30)/10
Practice makes perfect
We can simplify this expression by multiplying the expressions inside the radicals.
Now, let's rewrite the radical as a quotient of two radicals.
sqrt(6/20)=sqrt(6)/sqrt(20)
To rationalize a monomial denominator, we multiply the numerator and denominator by a radical that will eliminate the radical in the denominator.
Because the denominator is a square root, we need to multiply it by a square root that will give us a perfect square under the radical.
We know that we have successfully rationalized the denominator because the radical has been eliminated. However, our fraction can still simplified a bit further. Let's try!
