250 billion is 250,000,000,000

So, you can write it in scientific notation as:


2.5*10^(11)

Because you need to count the spaces from the decimal point to the last zero and elevated 10 to this power. So 250,000,000,000 is equivalent to:

2 . 5 0 0 0 0 0 0 0 0 0 0 x 10^11

1st 2nd 3rd 4th 5th 6th 7th 8th 9th 10th 11th
