Free logarithmic equation calculator - solve logarithmic equations step-by-step. Review Properties of Logarithmic Functions We first start with the properties of the graph of the basic logarithmic function of base a, f (x) = log a (x) , a > 0 and a not equal to 1. The following diagram should help you understand exactly what these numbers mean: If you would like a simpler solution, you can always press the [zoom] button on your calculator (it is next to the [window] button), and choose an option from the menu. For example, for log base 4 of x, enter either "log(x)/log(4)" or "ln(x)/ln(4).". Base to change to = Calculate × Reset. Check your work. Hence, all logarithmic functions are written with reference to an exponential base. Press the [y=] button on your calculator. log. Most graphing and scientific calculators have the ability to calculate logarithms, but you might come across questions which require you to use a different base than your calculator’s built-in functions.
