Question

solve ln (a +10) =2 ln (a-2)

Answer 1

Do you know the log rules?

Answer 2

The easiest way to go about it is using the rule.

ln (a+10) = ln (a-2)^2

Answer 3

You are allowed to bring the 2 from in front of the ln as an exponent. Now you can drop the ln an solve it as (a+10) = (a-2)^2. Can you handle it from here?
