The number that is irrational among the options provided is \( \sqrt{7} \) (square root of 7).
The square root of a non-perfect square (like 7) is an irrational number, meaning it cannot be expressed as a fraction of two integers.
On the other hand, the numbers 3.14, 23, and \( \sqrt{49} \) (which equals 7) are either rational (3.14 and 23) or a whole number (7).
So, the answer is:
- \( \sqrt{7} \) (square root of 7)
