For simplicity an irrational number in this case would not be a perfect square

Answer 2

try taking the square root of both of the numbers and adding them together. Which number gives you a non repeating decimal and which one gives you a perfect integer (eg. 1,2,3,4,..)

Answer 3

@VeritasVosLiberabit what

Answer 4

so first simply both answers. what is \[\sqrt{64}+\sqrt{5}=?\]

Answer 5

then what is \[\sqrt{64}+\sqrt{4}\]

Answer 6

69?

Answer 7

Answer 10

yes that sounds better, Does your calculator repeat a bunch of numbers after the decimal place?

Answer 11

Yes

Answer 12
