Find the logarithm with base 10 of number 100. Z is hence the answer to log x y. The log operator allows us to solve for X and write an equivalent expression as log 100 X.
In order to calculate log-1 y on the calculator enter the base b 10 is the default value enter e for e constant enter the logarithm value y and press the or calculate button.
It might sound like a tedious method but try a few examples first and you will see its actually pretty quick. Calculate Reset. Download Every FormulaThe All-in-one formula apphttpbitly2Hoz1cZDONT USE THIS METHOD FOR ACCURATE CALCULATIONIt is a simple trick to calculate log. If xz y then z is the answer to the log of y with base x ie log x y z In other words x needs to be raised to the power z to produce y.
