WebSubtracting terms with fractional exponents follows the same rules as adding terms with fractional exponents. The terms must have the same base a and the same fractional exponent n/m. The rule is given as: Can/m – Dan/m = (C – D)an/m Here’s an example of subtracting fractional exponents: 2x 2/5 – x 2/5 = x 2/5 Multiplying Fractional Exponents WebWhy this works. There are two ways to demonstrate the reason behind this formula. Explanation 1: If you expand the numerator and the denominator, you can see that we cancel several x's that are common factors. All that remains is x ⋅ x which, of course, is x 2 . Explanation 2: Rewrite the denominator as negative exponent and then simplify.
