Webb12 maj 2024 · Let us try to replace the number in the parenthesis with the base raised to an exponent. log 5 (25) = log 5 (52) One the base and the number in the parenthesis are identical, the exponent of the number is the solution to the logarithm. Therefore log 5 (25) = 2. Some more examples: log 2 (32) = log 2 (25) = 5. log 6 (1) = log 6 (60) = 0. WebbProperties of Logarithms. Let M and N arbitrary positive number such that a > 0, a ≠ 1, b > 0, b ≠ 1 then. log a MN = log a M + log a N. log a M N = log a M – log a N. log a N α = α log a N (α any real no;) log aβ N α = α β log a N (α ≠ 0, β ≠ 0) log a N = log b. ⁡.
