     log5(x + 4) = 2

Learn the definition rule carefully for writing a 
log equation as an exponential equation and vice-versa:
      
           This log equation:

         logB(A) = C

           is by definition equivalent to this exponential equation

               A = BC 

   
Using this definition rule,

     log5(x + 4) = 2

becomes:

           x + 4 = 52

           x + 4 = 25

               x = 21
