Step 1: Rewrite 8 as a power of 2. Since 8 = 2 3, we can rewrite the equation 2 x = 8 as: 2 x = 2 3. Step 2: Set the exponents equal. Now that the bases are the same (both are base 2), we set the exponents equal to each other: x = 3. Final Answer. The solution to the equation 2 x = 8 is x = 3. Highlights. Key point: 8 can be rewritten as 2 3.
