Chapter P.1, Problem 55E
Solution

To write the interest on school debt in scientific notation.

  1.7 247 ×1010

Given:

The interest on school debt is 17 247 millions or 17 247 000 000 .

Concept Used:

To write a number in scientific notation, move the decimal point after the first nonzero integer and raise the exponent of 10 by the number of digits we moved the decimal point.

If the decimal point was moved to the left, then raise the positive exponent and if the decimal point moved to the right, then raise the negative exponent.

Calculation:

In order to write the interest on school debt 17 247 000 000 in scientific notation, move the decimal point to 10 digits to the left and raise the exponent of 10 by 10, it follows

  17 247 000 000=1.7247 ×1010

Thus, the current expenditure in scientific notation is 1.7 247 ×1010 .
