Question 914797: #1. Find domain of logarithm and solution to equation: log(base 4) (x + 9) − log(base 4) (x − 9) = 3
#2. Rewrite the equation so it contains no logarithms:
log(base 5) (x + 5) + log(base 5) (x − 5) = 2 .
What would the domain be?
What would the smaller and larger values of the equation be?
Thank you

Number 2:
Base is 5, log is 2,
, domain can be all real numbers.
This is a quadratic equation and solving for x may give a greater and a lesser solution; just solve for x.
