How to Find Logarithm

Follow these steps to find the logarithm of a number with a specific base.

  1. Given base (b) and argument (a) to logarithm.
  2. Express a in terms of power of b: a = bresult.
  3. Apply natural logarithm to both sides.
  4. Divide both sides by \(\log_{e}{b}\)
  5. The value left on the right hand side is the logarithm value.
