Answer :
The expression is:
[tex]\frac{x^2}{x^{-6}}[/tex]And for the properties of the exponents we can rewritte the equation for:
[tex]\frac{x^2}{x^{-6}}=x^2\cdot x^6[/tex]and if we simplify it:
[tex]x^2\cdot x^6=x^8[/tex]In negative exponets would be like:
[tex]\frac{x^2}{x^{-6}}=\frac{1}{x^{-2}x^{-6}}=\frac{1}{x^{-8}}[/tex]
