Sometimes it is necessary to find logarithms to bases other than 10 and e. For example, logarithms to the base 2 are used in communications engineering. Your calculator can still be used but you need to apply a formula for changing the base. This leaflet gives this formula and shows how to use it.
Here is a formula to calculate logarithms to base 2 or log base 2. The formula is stated by \(\begin{array}{l}\log _{2}x=\frac{\log_{10}x}{\log_{10}2}\end{array} \)
