The answer you were given to this problem by Checkley is WRONG! YOU WERE CORRECT in saying that this is an irrational number. An irrational number is a REAL NUMBER, but it is one that is NOT rational. That is, it CANNOT be expressed as a quotient of two integers. Irrational numbers include radical expressions that do not come out even, such as , , etc. If the square root happens to be of a perfect square, such as , then it is considered to be rational. Your answer involves the square root of a number, 68, that is not a perfect square. Therefore it is an irrational number.

is a REAL but yet an IRRATIONAL NUMBER.
