• All logs must be to the same base in applying the rules and solving for values • The most common base for logarithms are logs to the base 10, or logs to the base e (e = 2.718281…) • Logs to the base e are called Natural Logarithms logex = ln x If y = exp(x) = ex Then loge y = x or ln y = x
Logarithm questions with answers are provided for students to solve them and understand the concept elaborately. These questions are based on the logarithm chapter of Class 9, 10 and 11 syllabi.
