Witrynalogarithms are just inverse functions of exponential functions so that the base and the exponents cancel and equal 1 .try this logany base (withthat number)=1. as well β¦ Witryna13 mar 2024 Β· Instead, from 2 x = 3 you get log ( 2 x) = log 3, then by properties of logs you get x log 2 = log 3, so x = ( log 3) / ( log 2). Now you can use any log function your calculator has to get as many decimals of x as your calculator will give you. Just take the log base 2 on both sides. You would get x = l o g 2 3.
