Business publications that discuss growth trends often use complex equations with fractional exponents. Fractional exponent can be used instead of using the radical sign(√). For example, 125 means "take 125 to the fourth power and take the cube root of the result" or "take the cube root of 125 and then take the result to the fourth power." x12 = 412. x12 = 2. Convert negative exponents into fractions to simplify them. In the variable example. How to solve a number elevated to a fraction. $ These worksheets will generate 20 fractions problems with exponents per worksheet. How can we define fractional exponents so that the Laws of Exponents remain consistent?Consider any fraction, say 1/2.
