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: Result: When. y

EX: log(10 / 2) = log(10) - log(2) = 1 - 0.301 = 0.699. If there is an exponent in the argument of a logarithm, the exponent can be pulled out of the logarithm and multiplied. log b x y = y × log b x
