For a complete lesson on dividing radicals, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to divide radicals by dividing the numbers that are inside the radicals together. Students also learn that if there is a square root in the denominator of a fraction, the problem can be simplified by multiplying both the numerator and denominator by the square root that is in the denominator. And if there is a cube root in the denominator of a fraction, the problem can be simplified by multiplying both the numerator and denominator by whatever it takes to create a perfect cube in the denominator.
