WebMar 6, 2024 · Logarithmic Functions. The logarithmic function equation is as shown, c = log b a for a>0 such that b>0 and b ≠ 1. This is read as “log a to the base b is equal to c” or “c is equal to the log a to the base b”. Also, if b c = a then only we can define l o g b a = c. Mathematically it means, to what power b must be raised, to yield a. WebSelect the output cell where we need to find out log value, i.e. K16 in this example.

Let: log_b(x)=y=> switch x and y: log_b(y)=x=> solve for y: b^[log_b(y)]=b^x y=b^x=> hence: log_b(x) and b^x are the inverse functions.
WebSometimes a logarithm is written without a base, like this: log (100) This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. 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) = log10(1000) = 3.
