Fido did not have fleas when his owners took him to the kennel. The number of fleas on Fido after he returned from the kennel grew according to the equation f = 8(3)ⁿ, where f is the number of fleas and n is the number of weeks since he returned from the kennel. (Fido left the kennel at week 0). How many fleas did Fido pick up at the kennel?
