It represents the exponent or power to which the base often 10 but sometimes 2 or another number must be raised to get the number that is in the argument of the log expression. Log 10 100 log 10 1000 log 10 100000. Log 10 n 10 x n Where x is the log 10 of n.
Hence log2 calculation can be done using the below formula Log2 n 2x n.
Log b x y y log b x Logarithm base switch rule. So 25 10 95367. In this formula FV is future value and is the variable youre solving for. It represents the exponent or power to which the base often 10 but sometimes 2 or another number must be raised to get the number that is in the argument of the log expression.
