To represent y as a function of x, we use a logarithmic function of the form y= logb(x) y = l o g b ( x). The base b logarithm of a number is the exponent by which we must raise b to get that number. We read a logarithmic expression as, “The logarithm with base b of x is equal to y ,” or, simplified, “log base b of x is y .”.Rewriting a logarithm in exponential form can make solving easier.
