For example, to divide (3 + 5i root 11) / (6 + 2i root 11), the first step is to multiply both the numerator and denominator of the fraction by the conjugate of the denominator, which is (6 — 2i root 11), then FOIL in both the numerator and denominator, and combine like terms.

For example, to simplify 7/12 divided by 7/9, first change the division sign to multiplication and flip the second fraction, to get 7/12 x 9/7. Next, multiply the fractions by first cross-canceling, then multiplying across the numerators and across the denominators.

Students are then asked to find missing side lengths of right triangles using the Pythagorean Theorem.

If a factor pairs up in the factor tree, then it comes out of the radical. If a factor does not pair up, then it stays inside. Students also learn to simplify a cube root by setting up a factor tree for the number inside the radical. If a factor is part of a group of three factors that are the same, then it comes out of the radical. If a factor is not part of a group of three factors that are the same, then it stays inside.
