Can the natural log be negative
WebNo, that’s not right: no matter what the base b, log b x is not defined for x ≤ 0. Recall that log b x = y means that b y = x. If b > 0 and b ≠ 1, no power of b is negative or 0, so the equation b y = x has no solution for x ≤ 0. We don’t define logs base b for b = 1 or b ≤ 0.
