Hank is incorrect because square roots of perfect squares are rational.
In this case, \( \sqrt{25} = 5 \), which is a rational number. The assertion that square roots are irrational is not true in general; it depends on whether the number is a perfect square or not. Since 25 is a perfect square, its square root is rational.
