the remaining figuration off a heater is given by him musical to minus, um, distance to the image divided by the distance to the object. Do you all? From the previous example, we can find distance to the images. Three hundred's under major. Where is the distance to the object we have is 27 27 point trees and you return deriding the stone numbers we get here. Brooks mentally 11 11. So the magnification we get here is 11. End off the problem. Thank you for watching.
