Answer:  2.5722 .
_____________________________________________________
 Explanation:
 _________________________________________________ 
              log(base "\pi" of 19  = y ?  ;  Solve for "y" ;
__________________________________________________
     \pi ^ (y)  = 19 ;  Solve for "y" ?
__________________________________________________
Take the "ln" (that is, "natural logarithm", of both sides:
__________________________________________________
           ln  [ \pi ^ (y) ]  = ln 19  ;
__________________________________________________
             y *  ln \pi = ln 19 .
__________________________________________________
     Use "3.1416" as an approximation for:  " \pi "  ;
__________________________________________________
             y * ln (3.1416) = ln 19 ;
__________________________________________________
  Divide EACH side of the equation by:  " [ ln (3.1416) ]" ; to isolate "y" on one side of the equation; and to solve for "y";  (Use a calculator to do this) ;
_________________________________________________________
            y *  ln (3.1416)  / [ ln (3.1416) ] = ln 19 / [ ln (3.1416) ] ;
________________________________________________________
           y = ln 19 / [ ln (3.1416) ] ;
 _______________________________________________________
           y = 2.5721639670047041 ; 
 
                  → round to nearest 4 (FOUR) decimal places;
_______________________________________________________
         → y = 2.5722 .
