Chapter P.1, Problem 53E

Solution

To write the current expenditures in scientific notation.

  $5.35665\times {10}^{11}$

Given:

The current expenditures are $535665$ millions or $535665000000$ .

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 current expenditures $535665000000$ in scientific notation, move the decimal point to 11 digits to the left and raise the exponent of 10 by 11, it follows

  $535665000000=5.35665\times {10}^{11}$

Thus, the current expenditure in scientific notation is $5.35665\times {10}^{11}$ .
