August undefined, 2024

WitrynaA logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation. For example, if 102 = 100 then log10 100 = 2. Hence, we can conclude that, Logb x = n or bn = x. Where b is the base of the logarithmic function. This can be read as “Logarithm of x to the base b is equal to n”. Witryna14 lis 2024 · we can use the following formula log b a = log c a log c b So, to change from the base B to base A : log B A = log A A log B A and, since log A A = 1, we get log B A = 1 log A B and log B A = log A B then ( log A B) 2 = 1 ⇒ log A B = ± 1 Therefore, A = B or A = B − 1 Share Cite Follow edited Nov 14, 2024 at 22:29 …
