In mathematics, a logarithm is the inverse of exponentiation. It answers the question: “To what power must a base be raised to produce a given number?” For example, since , we write . Logarithms are widely used in algebra, calculus, computer science, and real-world applications like measuring sound intensity (decibels), earthquake strength (Richter scale), and population growth. #Mathematics #Algebra #Logarithms #Exponents #MathLearning #STEM #StudyTips #MathHelp #Calculus #Numbers
