Answer:

Step-by-step explanation:

The given expression is

8 = 2^x + 4

The first step is to subtract 4 from the left hand side and the right hand side of the equation. It becomes

8 - 4 = 2^x + 4 - 4

4 = 2^x

The next step is to express 4 on the left hand side of the equation in powers of 2. It becomes

2^2 = 2^x

Since the two bases on the left hand side and the right hand side of the equation are equal, then the powers can be equated. Therefore

x = 2
