Answer: The irrational number is the square root of 3
Step-by-step explanation: The square root of 3 is an irrational number because it cannot be expressed as a finite or repeating decimal. When we try to calculate the decimal representation of the square root of 3, we will get an infinitely long, non-repeating sequence of digits after the decimal point. This means that the square root of 3 cannot be represented as a ratio of two integers and therefore it is an irrational number.
