Log

The abbreviation log x is often used when the intended base can be inferred based on the context or discipline, or when the base is indeterminate or immaterial. Log z = ln (r) + i (θ+2nπ) = ln (√ (x2 + y2)) + i ·arctan (y/x)) logarithm problems and answers problem #1 find x for log 2 (x) + log 2 (x -3) = 2 solution: Log 2 (x∙ (x -3)) = 2 changing.
