Answer: ![\frac{1}{3^6}=3^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%5E6%7D%3D3%5E%7B-6%7D)
Explanation: Denominators of a fraction can be equivalently written as their value to the power of negative 1. In this case the denominator expression itself has an exponent of 6, which taken to the power of negative one becomes -6:
![\frac{1}{3^6}=(3^6)^{-1}=3^{6(-1)}=3^{-6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%5E6%7D%3D%283%5E6%29%5E%7B-1%7D%3D3%5E%7B6%28-1%29%7D%3D3%5E%7B-6%7D)

recall that the axis of symmetry for a vertical parabola is simply the equation for the vertical line of the vertex's x-coordinate.
