Prior to the days, when digital memory chips and computers were not invented, it was really difficult to express very large numbers. To solve this problem, logarithm was invented in mathematics. Though evolution of digital technology makes it easier to express real large numbers, but logarithm questions and solutions have not lost their relevance in the academic world. In order to crack any major entrance test, aspirants need to practice solving logarithm questions. The questions in ExamTime Quiz come in MCQ format and are one of the best tools for exam preparation.
