#### Explanation:

Before we get rid of the exponent, we need to change it. Take a look at the rule below:

#a^-b = 1/(a^b)#

Given this law, let's apply it to the problem.

#-7^-1 = 1/(-7^1)#

Now that we got rid of the negative, we can eliminate the exponent as a whole. Recall that anything to the first power is itself.

#1/(-7)#

This can be rewritten as:

#-1/7#
