2.5 x 109 is wrong.

2.5 x 109 would be "2500000000

The correct answer is 2.5 x 1010 or 25 x 109 (But this would not be in true scientific notation). Scientific notation is basically calculated by how many times you would move the decimal point (as a result of multiplying by 10). As follows.

2.5 x 109 = 2500000000

2.5 x 1010 = 25000000000

Not sure how old this question is but thought i would answer anyway.
