[(rad 50 + rad 32 - rad 8) x (rad 12 + rad 27) - rad 600] : (5 rad 6) x (rad 3)^2 + 4^2 = [(5 rad 2 + 4 rad 2 - 2 rad 2) x (2 rad 3 + 3 rad 3) - 10 rad 6] : (5 rad 6) x 3 + 16 = (7 rad 2 x 5 rad 3 - 10 rad 6) : (5 rad 6) x 3 + 16 = (35 rad 6 - 10 rad 6) : (5 rad 6) x 3 + 16 = (25 rad 6) : (5 rad 6) x 3 + 16 = 5 x 3 + 16 = 15 + 16 = 31
