In mathematics, a logarithm is the exponent to which a base must be raised to produce a given number. Logarithms are used to solve a variety of problems, including those involving exponential growth and decay. When adding logarithms with different bases, it is important to first convert them to the same base. This can be done using the change of base formula.
Once the logarithms have been converted to the same base, they can be added together. The sum of the logarithms is equal to the logarithm of the product of the original numbers. For example, loga(x) + loga(y) = loga(xy).
