Okay, so you are talking about exponents, so in here we have to multiply, but we are NOT going to multiply 81 x 9, because that would give us an incorrect answer. Instead we are going to multiply 81 x 81 x 81 x 81 x 81 x 81 x 81 x 81 x 81, and the answer is 120,094,635,296,999,121. That's a very long number, so there you have it.
