The given problem is:
.
%28-13%29%5E-1
.
The rule to follow for this problem is:
.
A%5E%28-n%29+=+1%2FA%5En
.
To use this rule on the given problem let A = (-13) and -n = -1 and n = 1
.
Using the rule we get:
.
%28-13%29%5E%28-1%29+=+1%2F%28-13%29%5E1+=+-1%2F13
.
Note that the right side of this equation simplifies to 1%2F%28-13%29 or just -1%2F13.
.
Hope this problem helps you to understand the meaning of negative exponents and how to
get rid of them.
