To solve the equation log(x) = 2, we need to interpret what this logarithmic expression means. The function log represents a logarithm to the base 10, which is the common logarithm. This means we are looking for the value of x that makes the equation true under the assumption that the logarithm is base 10.

The equation log(x) = 2 can be rewritten in exponential form. The definition of a logarithm states that if log_b(a) = c, then b^c = a, where b is the base of the logarithm. In this case, we can convert log(x) = 2 to its equivalent exponential form:

10^2 = x.

Now, calculating 10^2 gives us:

10^2 = 100.

Thus, the value of x that satisfies the equation log(x) = 2 is 100. Therefore, the correct answer is indeed 100.
