Solve the following equations, if possible. Rewrite each logarithmic equation in its equivalent exponential form. Rewrite each exponential equation in its equivalent logarithmic form. Which is read “ y equals the log of x, base b” or “ y equals the log, base b, of x.” This is read as “ y equals the log of x, base 2” or “ y equals the log, base 2, of x.”Ī logarithmic function is a function of the form This equation is rewritten as y = log 2 x. The word logarithm, abbreviated log, is introduced to satisfy this need. If x = 2 y, then y = (the power on base 2) to equal x. If x = 2 ywere to be solved for y, so that it could be written in function form, a new word or symbol would need to be introduced.
