Answer:
(9/8)^-1 = 8/9
Step-by-step explanation:
To re write without an exponent means we will eliminate it's power.
This fraction came with the power of -1.
And when the power of a fraction or a whole number comes with power of -1 what it simply means it's the inverse of the number.
So let's evaluate the above fraction.
(9/8)^-1 = 1/(9/8)
(9/8)^-1 = 1*(8/9)
(9/8)^-1 = 8/9
