The difference is that while the exponential form isolates the The logarithm log b (x) = y is read as log base b of x is equals to y. log m n = n log m. For x > 0, y = log(x) is equivalent to 10y = x. Logarithms are used to do the most difficult calculations of multiplication and division. Next, we have the inverse property. Example 4: The value of log 2, to the base 10, is 0. Try It 9. log b x y = y × log b x.That is, for any real number x, = ⁡ =. The operation is a special case of the logarithm, i.
