-
- log 75/16-2 log 5/9+log 32/243
= log 75/16-log(5/9)^2+log32/243
= log 75/16-log25/81+log 32/243
=log((75/16*32/243)/(25/81))
= log(75/16*32/243*81/25)=log 2 - 12 years agoHelpfull: Yes(29) No(0)
- we know that log(x/y)2= 2log(x/y)
here 2log5/9 = log(5/9)2= log(25/81)
log(75/16)-log(25/81)+log(32/243)
=log(75/16*81/25)+log(32/243)
=log(243/16)+log(32/243)
=log(243/16*32/243)
=log(2)=0.2010 - 12 years agoHelpfull: Yes(11) No(0)
