Logically

A logarithm is the opposite of exponentiation. If you have a number raised to a certain power (like 2^3 = 8), the logarithm asks, "To what power must we raise this base (2) to get the number (8)?" So, log base 2 of 8 is 3 because 2 raised to 3 equals 8. Logarithms help us understand how many times we multiply a number by itself to reach another number, making them useful for dealing with very large or very small numbers, or in fields like science, engineering, and finance.
