Hi! I'm happy to help!
To solve this, we need to simplify this expression as much as possible. We see that in the exponent, we have the expression 6-9, which we can substitute for -3.

![x^(-3)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/w0yf2ifz7x482eks3p950w2gwgfgd7zbaw.png)
To further simplify, we need to find out what
is. Whenever using a negative exponent, follow this equation.
=
![(1)/(x^(y) )](https://img.qammunity.org/2021/formulas/mathematics/high-school/2x0zlvzt5s4l8yh00bbncf5f2tc0df8m0s.png)
Using this, we can turn
, into
. Since we do no know what x is, we cannot simplify any further.
To sum it up,
is an equivalent expression for
.
I hope this was helpful, keep learning! :D
