Question

Which expression is irrational? (1 point)

8 over 5.
square root of 4
square root of 10.
square root of 64

Answer 1

Is this a test question?

Answer 2

kinda it is a practice test

Answer 3

Oh ok

Answer 4

I wonder if a practice test is against the rules

Answer 5

Practice tests (that are *not* counted as a grade) are acceptable to answer on QC

Anyway, for anyone looking up this question in the future ----> square roots of non-perfect squares are irrational (ex: sqrt(4) is rational because 4 is a perfect square, while sqrt(5) is not, because 5 is not a perfect square). repeat this logic with the answer choices.
