This is not an equation to be solved.

This is a statement rather than an equation to be solved, because there is no variable.

-8 can be written as $- 2^{3}$ $-2^3$

$- 2^{3} = - 2^{3}$ $-2^3 = -2^3$

However, if the question had read
Solve $- 2^{x} = 8$ $-2^x = 8$

Use the fact shown above.

$- 2^{x} = - 2^{3}$ $-2^x = -2^3$
So $x = 3$ $x = 3$

How do you solve -2^3 = -8−23=−8-2^3 = -8?
