The operation that Pete is using is the operation of multiplying numbers by decimal numbers and the power of 10 involved is 4

If Pete must move a decimal point to the left in 4 places, then the operation she is using is the operation of multiplying numbers by decimal numbers.

Since the movement is to the left in 4 places, the power of 10 involves will be a 4

For example,

if we are to convert 0.56 say to scientific notation to the power of 4. We will need to move the decimal point to the left 4 times to have 0.000056 * 10^4
