*** Disregard this WRONG solution!! *** I read the question too fast! Why do you make it so complicated? Step 1: Add the three LHS terms together to get 3 * 9^a = 18 Step 2: Divide both sides by 3 to get 9^a = 6 Step 3: Now take the log of both sides to get a * log(9) = log(6) Step 4: Divide both sides by log(9) to get a = log(6) / log (9) Step 5: Using a calculator evaluate log(6) / log(9) to get a = 0.8154 (approx) You don't need to break up logs in to separate parts all the time; it can be very confusing.

Sorry, but your solution is uncorrect... a=0.4385

@@tomtke7351You are right - my bad. I ADDED the three 9^a terms instead of multiplying them. A very silly mistake to make; I read the question too fast. A well-deserved slap on the wrist! Thanks.
