Select the irrational number? a)√9 b)√12 c)√16 d)√20 e)√25 (there should be more than one answer)

The answers are:

    [B]:  "√12 " ;   AND:

    [D]:  "√20" .

Note:  "Irrational numbers" have decimals that are:  1) non-terminating;  AND:  2) non-repeating.

Consider the answer choices given; and consider the given information that there "should be no more than one answer.

Consider the following answer choices:

Choice A)  "√9"  =  3 .  Rule out this choice.

Choice C)  "√16" = 4 .  Rule out this choice.

Choice E)  "√25" = 5.   Rule out this choice.

We are left with 2 (two) remaining answer choices:
    [B]:  "√12"  ;  and:  [D]:  "√20" .

If there are more than one answer, then these two choices should be the correct answer.   However, let us explore these two choices, using a calculator.

    [B]:  "√12"  =  3.4641016151377546
