Question

What’s is the answer

Answer 1

C

Explanation:

Taking a square root of a number that doesn't have a square root like
`√(17)` will result in an infinite number of random digits which is an irrational number. Hence, C is the answer.

D isn't the answer because even though
`√(5)` is irrational, you're adding
`√(5)` and then subtracting
`√(5)` from the total sum. Hence the total sum would be 5+14.

5+
`√(5)`+14-
`√(5)` =5+14+
`√(5)`-
`√(5)`= 5+14 ==> 19 is a rational number
