GMAT Question of the Day Solution
This question of the day presents an exponents work-out. First rule of GMAT: Know your fundamentals! Do you really know your exponent rules? The GMAT will push you to the limits. Here’s a little trick: If you get confused on a question with gigantic numbers, use smaller numbers to figure out the rules. In this case notice that we are raising to a power. That means that all of the exponents need to be multiplied. So 3*1000*1000*2 = 6,000,000. So the answer is 10^6,000,000.
