During a training exercise on data modeling, an analyst needs to solve the equation log⁡x64=2\log_x 64 = 2 to find an unknown base factor. Converting this to the exponential form x2=64x^2 = 64 gives the possible solutions 8 and -8. The analyst must discard -8 because a fundamental rule states that the base of a logarithmic function must always be ____.
