Answer:
[tex]\frac{n^2}{36}[/tex]
Step-by-step explanation:
This is where knowing the exponent rules come into play. The negative exponent applies for both 6 and 2.
The negative exponent rule is basically reciprocal of x. So, if x is the numerator, it gets moved to the denominator, and vise versa. Also, the power of a power applies here too with the implied 1st power.
[tex](\frac{6}{n} )^{-2}\\(\frac{n}{6} )^{2}\\(\frac{n^{2}}{6^2} )\\\frac{n^2}{36}[/tex]
