Answer:

#64#

Explanation:

We will be using the BEDMAS THEORY:
Brackets, Exponent, Division, Multiplication, Addition, and Subtraction.

Knowing this, we start with what is inside the bracket

#-2xx4= -8#

Then we go to the exponent.
#(-8)^2#
That equals #64#

This is due to the fact that #-8 xx -8 = 64#
(the negatives multiply to give a positive. )
