Step-by-step explanation:
Remove the parenthesis
16 - 17
= -11
the answer is b. this is because an irrational number goes on infinity in random digits. so if something is square rooted and not a perfect square it's going to be irrational. square root of 144 is 12 and 11/22 is 1/2 while 1 3/5 is 1.6 and the square root of .65 is .8062257 and so on.
