Logarithmic Equation Calculator - Symbolab
To solve a logarithmic equations use the esxponents rules to isolate logarithmic expressions with the same base. Set the arguments equal to each other, solve the equation and check your answer. A logarithmic equation is an equation that involves the logarithm of an expression containing a varaible.
3 Ways to Solve Logarithms - wikiHow
Aug 6, 2024 · To solve a logarithm, start by identifying the base, which is "b" in the equation, the exponent, which is "y," and the exponential expression, which is "x." Then, move the exponential expression to one side of the equation, and apply the exponent to the base by multiplying the base by itself the number of times indicated in the exponent.
