Opportunities and Realistic Risks

Q: Can I simplify a fraction with a rationalized denominator?

To rationalize a denominator with a cube root, students multiply both the numerator and denominator by an expression that will eliminate the cube root. For example, to rationalize the denominator of 3 / ∛2, students would multiply both the numerator and denominator by ∛2, resulting in (3 × ∛2) / (∛2 × ∛2 × ∛2) = 3∛2 / 2.

Rationalizing denominators involves removing any radicals (square roots) from the denominator of a fraction. To do this, students multiply both the numerator and denominator by an expression that will eliminate the radical. For example, to rationalize the denominator of √2 / 2, students would multiply both the numerator and denominator by √2, resulting in (√2 × √2) / (2 × √2) = 2 / √2. This simplified fraction is easier to work with and understand.
