Answer:

index = 9; exponent = -8

Explanation:

When dealing with fractional exponents, simply remember that the exponent is always the numerator and the index is always the denominator:
x^{(exponent)/(index )

You can simply remember that e comes before i in the alphabet to remember that exponent comes before index.
