Frequently Asked Questions (FAQs)
A logarithm answers the question: to what power must the base be raised to produce a given number? For example, log base 10 of 100 is 2 because 10² = 100.
Common logarithms have base 10, written as log₁₀(x). Example: log₁₀(1000) = 3.
Natural logarithms use base e (Euler’s number, ~2.718). They are written as ln(x). Example: ln(e) = 1.
No. Logarithm base must be greater than 0 and not equal to 1.
Logarithms are used in mathematics, physics, engineering, finance, computer science, and algorithms such as time complexity analysis.
