Question

How do you solve `-2^3 = -8`?

Answer 1

This is not an equation to be solved.

Explanation:

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`

However, if the question had read
Solve `-2^x = 8`

Use the fact shown above.

`-2^x = -2^3`
So `x = 3`
