In arithmetic, a logarithm is the exponent to which a base should be raised to supply a given quantity. Logarithms are used to resolve quite a lot of issues, together with these involving exponential progress and decay. When including logarithms with totally different bases, you will need to first convert them to the identical base. This may be finished utilizing the change of base formulation.
As soon as the logarithms have been transformed to the identical base, they are often added collectively. The sum of the logarithms is the same as the logarithm of the product of the unique numbers. For instance, loga(x) + loga(y) = loga(xy).
