$64$

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. )
