How to Calculate Logarithms?

Answer

To calculate logarithms, get a scientific calculator with “log” functions on it; use the “Change of base” formula. Convert the standard form logarithms into a ratio and format you can type into a calculator. For any log in standard form, use log b (subscript) x (variable) = log 10 (subscript) x (variable)/log 10 (subscript) b (variable). Once the conversion is complete, you will have a new form to enter into your calculator; enter your ratio. Press the “log” key on the calculator and then hit the value of x; this is the number you already determined earlier in Step 2. Next, press the division key on the keypad, press the “log” button again and the “equals” or “exe” key. You will see the value of the logarithms on the display.
