Answer:
Step-by-step explanation:
given,
log₅ (12500)
using logarithmic identity
logₐ a = 1
logₐ x³ = 3 logₐ x
log (ab) = log a + log b
logₐ x =
now,
log₅ (12500)
log₅ (5³ × 100 )
log₅ (5³) + log₅(100)
3 log₅ (5) + log₅ (10²)
3 + 2 log₅ (10)
hence, the required solution is given above.
Re write it in so that to have one single entity on the left & same on the right
log(x-1)-log5 = log[(x-1)/5]
and log(x+1)-logx = log[(x+1)/x]
So:
log[(x-1)/5] = log[(x+1)/x] ==> (x-1)/5 = (x+1)/x
Now you can solve it: x(x-1)=5(x+1)
==> x² - 6x -5 =0
Solving this quadratic equation gives x'=3+√14 & x" =3-√14
