Convert in x=y to exponential form

x = e y

Step-by-step explanation:

Simply consider the fact that, if  log ( x ) = y , than also  e log ( x ) = e y  must hold. Now use the fact that the exponential function  e x  is the inverse of the logarithmic function  log ( x ) , which means that  e log ( x ) = x , and thus the solution.
