Explanation:
_________________________________________________
log(base "[tex] \pi [/tex]" of 19 = y ? ; Solve for "y" ;
__________________________________________________
[tex] \pi [/tex] ^ (y) = 19 ; Solve for "y" ?
__________________________________________________
Take the "ln" (that is, "natural logarithm", of both sides:
__________________________________________________
ln [ [tex] \pi [/tex] ^ (y) ] = ln 19 ;
__________________________________________________
y * ln [tex] \pi [/tex] = ln 19 .
__________________________________________________
Use "3.1416" as an approximation for: " [tex] \pi [/tex] " ;
__________________________________________________
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 .
