Answer:

The answer is option C

Explanation:


\frac{ {6}^( - 3) }{ {6}^(5) }

Using the rules of indices

Since the bases are the same and are dividing we subtract the exponents

That's


\frac{ {a}^(x) }{ {a}^(y) } = {a}^(x - y)

So we have


\frac{ {6}^( - 3) }{ {6}^(5) } = {6}^( - 3 - 5) = {6}^( - 8)

Using the rules of indices


{x}^( - y) = \frac{1}{ {x}^(y) }

So we have the final answer as


\frac{1}{ {6}^(8) }

Hope this helps you
