Step-by-step explanation: you need to move the decimal over 2 spots because it needs to be a number from 1-9. So it would be 4.26. Then the exponent is positive 2 because you are moving the decimal to the left.
Bit by bit clarification: you have to move the decimal more than 2 spots since it should be a number from 1-9. So it would be 4.26. At that point the type is positive 2 since you are moving the decimal to one side.
