To convert a measurement, Pete must move the decimal point to the left 4 places. This is a shortcut for an operation. Which operation is he using? Which power of 10 is involved?

1 answer

Moving the decimal point to the left 4 places corresponds to dividing a number by \( 10^4 \). This is because each time you move the decimal point to the left, it effectively divides the number by 10. Therefore, if Pete is moving the decimal point to the left 4 places, he is performing the operation of division by \( 10^4 \) (which is 10,000).
