If we have a common ratio every set amount of time (and not a common difference or addition), this is an exponential relationship. An exponential equation would have a form like Money = (1000)(2)^(# of months), where every additional month would cause the money amount to double.
I would use long division to show my work. But I can tell you the answer. The answer is 121.
U basically solve: (4sqrt8)*2 + (5 sqrt 12 + 6 sqrt 20)*2
the answer is the bottom one
