Plots of logarithm functions, with three commonly used bases. The special points log b b = 1 are indicated by dotted lines, and all curves intersect in log b 1 = 0.

log b (x) = log c (x) / log c (b) For example, in order to calculate log 2 (8) in calculator, we need to change the base to 10: log 2 (8) = log 10 (8) / log 10 (2)

On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number. Example: log(1000) = log 10 (1000) = 3

Apr 21, 2025 · Expressed mathematically, x is the logarithm of n to the base b if b x = n, in which case one writes x = log b n. For example, 2 3 = 8; therefore, 3 is the logarithm of 8 to base 2, …
