Outline of Rational Expressions UNIT TEST. That is okay, we just need to avoid division by zero. The second rational expression is never zero in the denominator and so we don’t need to worry about any restrictions. \[a^{\tfrac{1}{n}}=\sqrt[n]{a}\] We can also have rational exponents with numerators other than \(1\).
