Logarithm is an important topic that needs to be prepared well for the Quantitative Aptitude section of exams. It requires practicing a lot of questions within a time limit. The logarithmic function is the inverse of the exponential function. It is defined as: y = log a x, if and only if x = a y; for x > 0, a > 0, and a ≠ 1.
