Question 75947
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.
{{{highlight((x-4)(x+1)=5^3)}}}
Rememeber that even when you solve this, you need to check your solutions and make sure they aren't extraneous.
Happy Calculating!!!!
