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.
![((6)/(n) )^(-2)\\((n)/(6) )^(2)\\((n^(2))/(6^2) )\\(n^2)/(36)](https://img.qammunity.org/2022/formulas/mathematics/high-school/ak2ahi7kkq0kdt0b7dlatp56asnurak4k5.png)
