One over one hundred billion in a negative exponent would be 1 x 10-9
The answer is 107. A thousand is 103, a million is 106, a billion is 109, a trillion is 1012, and a quadrillion is 1015. You will notice the exponent is evenly disvisible by 3 in each case. Ten million, ten billion, ten trillion, and so on adds 1 to each exponent, and one hundred million, one hundred billion, etc. adds 2 to each exponent. Adding three to the exponent moves it to the next number. In other words, a thousand quadrillion is a quintillion.
