Problem 3 (5 points) Which of these 3 commands is different from the other two (circle it) 1 + 2 * 3 / 5+ 6^2 1+23 / (5 + 6^2) 1+ ((2+3)/5) + 6^2 Problem 4 (5 points) Snell's law describes why objects appear to bend when put into water (like a straw). It involves four values: 2 refractive indices that depend on the different mediums and two angles and is given by = n2 sin (01) sin (02) N1 Suppose in an experiment, you know that n = 2, 72 = 3 and 01 = T /4. Solve algebraically for sin (02) and then compute the numeric value of 02 in radians using the
