$- 15 = {(- 2)}^{8} + b$

Step 1

Since $b$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

${(- 2)}^{8} + b = - 15$

Step 2

Raise $- 2$ to the power of $8$ .

$256 + b = - 15$

Step 3

Move all terms not containing $b$ to the right side of the equation.
