Can someone simplify this! I need to know the exponent!

( I will give brainliest to the correct answer/explanation)

Thank you ❤️

*Accidentally turned f into r*

Step-by-step explanation:

Fractional exponents are actually quite simple :) I'll give a few examples and I'm sure you'll get it quick:

As you can see, the numerator of the fraction becomes an exponent, and the denominator becomes a radical.

So to simplify this question first make into An exponent raised to another exponent is the same as multiplying the exponents.  Thus, we can multiply 1/3*-9.

Then we can use what we learned earlier to make it:

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
