#-32#

Explanation:

The exponent represents the number of times that #(-2)# is multiplied by itself.

The easiest way to evaluate this, is to rewrite it out like such:

#(-2)(-2)(-2)(-2)(-2)#

From here it is just simple multiplication:

#(-2)(-2)(-2)(-2)(-2)#

#(4)(-2)(-2)(-2)#

#(4)(4)(-2)#

#(16)(-2)#

#(-32)#
