a) rad(25 + 225/16) = rad(625/16) = 25/4

b) rad(9 + 81/16) = rad(225/16) = 15/4

c) rad(49 + 784/9) = rad(1225/9) = 35/3

d) rad(16 + 400/144) = rad(2704/144) = 52/12 = 13/3

e) rad(1521/25 - 9) = rad(1296/25) = 36/5

f) rad(1600/9 + 100) = rad(2500/9) = 50/3

g) rad(3136/225 + 49) = rad(14161/225) = 119/15
