Rewrite the following without an exponent.

(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
