Question

State the index of the radical and exponent of the variable when the expression x^-8/9 is converted to a radical.

Answer 1

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.
