How to solve logarithms by hand
WebTo solve logarithmic equations, we have to use the laws of logarithms to rewrite the expressions in a more convenient way. After simplifying and reducing the logarithmic expressions, we will generally get one of two types of logarithmic equations. ... Solution: We can use the product law to form a single logarithmic expression on the left hand ... WebThe first type of logarithmic equation has two logs, each having the same base, which have been set equal to each other. We solve this sort of equation by setting the insides (that is, setting the "arguments") of the logarithmic expressions equal to each other. For example: Solve log 2 (x) = log 2 (14).
