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?

Answer 1

When Pete moves the decimal point to the left 4 places, he is effectively dividing the original number by \( 10^4 \) (which is 10,000). This movement to the left corresponds to a division operation because it reduces the value of the number.

So, the operation he is using is division, and the power of 10 involved is \( 10^4 \).
