💡 What Is a Logarithm?
A logarithm answers the question: “To what exponent must the base be raised to get a certain number?” For example, log base 10 of 100 is 2 because 10² = 100. Algebra, calculus, computer science, and engineering all rely on logarithms — especially when dealing with exponential relationships or solving for time, growth, or decay.
