In arithmetic, a logarithm is the exponent to which a base have to be raised to provide a given quantity. Logarithms are used to resolve quite a lot of issues, together with these involving exponential development and decay. When including logarithms with totally different bases, it is very important first convert them to the identical base. This may be executed utilizing the change of base system.
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).
