Question

solve log x -log (x-1) = log 3,find x​

Answer 1

hey !!

solve log x -log (x-1) = log 3,find x

Solution:--

log x -log (x-1) = log 3,

=>log [x/(x-1)] = log 3

=> x/(x-1)= 3

=>x = (x-1)3

=> x = 3x -3

=>2x =3

=>x= 3/2

Important formula

(1) log a - log b = log a/b

(2) if log a = log b

so, a=b
