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^(6-9)


x^(-3)

To further simplify, we need to find out what
x^(-3) is. Whenever using a negative exponent, follow this equation.


x^(-y)=
(1)/(x^(y) )

Using this, we can turn
x^(-3), into
(1)/(x^(3)). Since we do no know what x is, we cannot simplify any further.

To sum it up,
(1)/(x^(3)) is an equivalent expression for
x^(6-9).

I hope this was helpful, keep learning! :D
