That number is 2,500,000,000 so you could express it as 2.5 x 10^9

2,500,000,000

That is 2.5 billion. There are 9 decimal places to the billion so it is: 2.5 x 10^9. But since you want it to the one million mark it would be:

2.500x10^9 . The extra zeros take it to the one million point of accuracy.
