Exercise 68 Page 627

To rationalize a monomial denominator, multiply the numerator and denominator by a radical that will eliminate the radical in the denominator.

16sqrt(3)/3

Practice makes perfect

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.

16/sqrt(3)

a/b=a * sqrt(3)/b * sqrt(3)

16sqrt(3)/sqrt(3) * sqrt(3)

sqrt(a)* sqrt(a)= a

16sqrt(3)/3
