log6 (x+ 41) - log6 (x+1) =
2
First we will find the
domain.
==> x+ 41>0 ==> x >
-41
==> x + 1 > 0 ==> x >
-1
==> Then the domain is x > -1
.....(1)
We will use the logarithm properties to solve for
x.
We know that log a - log b= log
(a/b)
==> log6 (x+41) / (x+1)
=2
Now we will rewrite using the exponent
form.
==> (x+41)/(x+1) =
6^2
==> (x+41)/ (x+1) =
36
Multiply by x+1
==>
x+ 41 = 36(x+1)
==> x+ 41 = 36x +
36
==> 35x =
5
=> x = 5/35 =
1/7
==> x= 1/7 > -1 ( then the solution
within the domain.)
Then the solution is x=
1/7
