To evaluate a number with a negative fraction exponent, you need to take care of two things.
1) The negative exponent.
2) The fraction as an exponent.
1) Negative exponent
2) Fractional exponent
![a^{\frac{m}{n}} = \sqrt[n] {a^m} = (\sqrt[n]{a})^m](https://tex.z-dn.net/?f=%20a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%20%5Csqrt%5Bn%5D%20%7Ba%5Em%7D%20%3D%20%28%5Csqrt%5Bn%5D%7Ba%7D%29%5Em%20)
Example:
Evaluate
First, take care of the negative exponent.
Now we take care of the fractional exponent by using a root.
![= \dfrac{1}{\sqrt[3] {8^2}} = \dfrac{1}{(\sqrt[3] {8})^2} =](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B1%7D%7B%5Csqrt%5B3%5D%20%7B8%5E2%7D%7D%20%3D%20%5Cdfrac%7B1%7D%7B%28%5Csqrt%5B3%5D%20%7B8%7D%29%5E2%7D%20%3D)
1) The negative exponent.
2) The fraction as an exponent.
1) Negative exponent
2) Fractional exponent
Example:
