3. 2 x 10^11
4. 3 x 10^11
The closest estimation of $278,560,125,00 is $2.79 x 10^11.
To find the closest estimation of the federal debt, we need to convert the given number into scientific notation.
The given federal debt is $278,560,125,000.
To express this number in scientific notation, we need to move the decimal point to the left or right so that we have a number between 1 and 10.
In this case, we need to move the decimal point 11 places to the left, resulting in a value of $2.78560125.
Now, we multiply this value by 10 raised to the power of 11 to account for the decimal point movement.
So, the closest estimation of the federal debt in scientific notation is 2.79 x 10^11.
Therefore, the correct answer is 1. 2.79 x 10^11.
