You can put this solution on YOUR website!
log base 5^(x-4) + log base 5^(x+1)=3. Use the product rule for logs.
log base 5^ (x-4)(x+1)=3 Rewrite as an exponential eqaution.

Rememeber that even when you solve this, you need to check your solutions and make sure they aren't extraneous.
Happy Calculating!!!!
