Evaluate log base 2 of 8.

Explanation:
Logarithms tell us the exponent needed to reach a number with a given base. Here, we’re looking for the exponent x such that 2^x = 8. Since 8 is a power of 2, 8 = 2^3, so x = 3. Therefore, log base 2 of 8 equals 3. Quick checks: 2^2 = 4, 2^1 = 2, and 2^8 = 256, so the exponent that gives 8 is indeed 3.
