#-1#

Explanation:

#(-1)^7#
= #(-1)^2times(-1)^2times(-1)^3#
= #1times1times(-1)#
=#-1#

OR you could think that 1 to the power of anything will be 1 and for the negative sign, when the power is odd, the answer will include a negative and when the power is even, the answer will not include a negative
