Which statement is correct about √11?

Answer and explanation

Correct answer: It is irrational

A square root of a positive integer is rational only when the integer is a perfect square. The nearby perfect squares are 9 and 16, and 11 is neither of them. Therefore √11 cannot be written as a ratio of integers and is irrational. It is nevertheless a real number, because it has a point on the real number line and a positive decimal value approximately 3.316. It is not an integer or a natural number, since squaring any integer does not give 11; it is certainly not zero because 0² = 0, not 11. Thus option A is the only correct statement. The key test is whether the radicand is a perfect square, not whether the root symbol appears in the expression.
