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#
