Answer 2

irrational means that it can't be expressed as a fraction, and if you find the square root of each then you will see that one of them cannot be expressed as a fraction
square root of 62 = 8 = 8/1
sqrt(256)=16=16/1
sqrt(100)=10=10/1
sqrt(80) which is about 8.94427 can't be written as a fraction, so the answer is D. 80
