Question 543473
log(n+9)= log(4n)
---
Certainly if log(A) = log(B), A must equal B.
-----------------------------
Your Problem:
n+9 = 4n
3n = 9
n = 3
====================
Another way to get to the same answer:
log(n+9)= log(4n)
---
Write each side as an exponent of 10:
10^(log(n+9)) = 10^(log(4n))
----
Then n+9 = 4n
and 3n = 9
so n = 3
