but off the given problem Focal end is given from given by our or two artists Radius Reacher substrate in the value off, which is a three centimeter divided by two. This gives us the focal Indo from minus 1.5 centimeter. Um, in part B, then we can find a power. Uh, power will be so volatile with the routine is the one where if and, um, we have focal and we just found these minus 1.5 times gentle reminders to meter. So this gives us minus 66.7 the doctors.
