Sign In
To rationalize a monomial denominator, multiply the numerator and denominator by a radical that will eliminate the radical in the denominator.
3sqrt(15)/20
To simplify the given expression, we can first rewrite each radical as a quotient of two radicals.
sqrt(3/16)* sqrt(9/5)=sqrt(3)/sqrt(16)* sqrt(9)/sqrt(5)
Calculate root
Multiply fractions
Finally, we can rationalize the denominator of the quotient. 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.
a/b=a * sqrt(5)/b * sqrt(5)
sqrt(a)*sqrt(b)=sqrt(a* b)
a^m*a^n=a^(m+n)
sqrt(a^2)=a
Multiply
We know that we have successfully rationalized the denominator because the radical has been eliminated.
