The logarithmic function, y = log b (x) is the inverse function of the exponential function, x = by. So if we calculate the exponential function of the logarithm of x (x>0), f (f -1 (x)) = blogb(x) = x. Or if we calculate the logarithm of the exponential function of x, f -1 (f (x)) = log b (bx) = x.
In mathematics log x usually means to the natural logarithm (base e). [11] [12] In computer science and information theory, log often refers to binary logarithms (base 2). The following table lists common notations for logarithms to these bases.
What are Logs in Math? Logs are the other way of writing exponent. The formula for conversion between exponential and log forms is: b x = a ⇔ log b a = x. Logarithms are very useful in solving equations involving exponents.
Free Logarithms Calculator - Simplify logarithmic expressions using algebraic rules step-by-step.
This log calculator (logarithm calculator) allows you to calculate the logarithm of a (positive real) number with a chosen base (positive, not equal to 1). Regardless of whether you are looking for a natural logarithm, log base 2, or log base 10, this tool will solve your problem.
There are mainly 4 important log rules which are stated as follows: product rule: log b mn = log b m + log b n. quotient rule: log b m/n = log b m - log b n. power rule: log b m n = n log b m. change of base rule: log a b = (log c b) / (log c a)
