Irrational. The square root of a positive integer is either an integer (that is, if the integer is a perfect square), or an irrational number.

Yes. The square root of a positive integer can only be an integer (if your integer is a perfect square), or an irrational number (if it isn't).

No because its square root is an irrational number

Yes. The square root of any positive integer can only be either an integer (if the number, for example 49, happens to be a perfect square), or an irrational number.

Assuming your number is an integer: if the number is a perfect square, the number is of course an integer, and therefore rational. If the number is NOT a perfect square, it is irrational.

The square root of 2 is irrational. In general, the square root of a positive integer is either an integer (if you take the square root of a perfect square), or it is irrational.

The square root of 27 is an irrational number

Because 9 is a perfect square - which means that its square root is an integer. 3 is not a perfect square.

It is irrational. * The square root of any positive integer, except of a perfect square, is irrational. * The product of an irrational number and a rational number (except zero) is irrational.

No, its a rational number.No. 100 is rational- in fact an integer and a perfect square.

The square root of ANY positive integer is either a whole number, or an irrational number. Only the perfect squares have whole number square roots; all the rest are irrational. 97 is not a perfect square therefore √97 is irrational.

It is rational. The root of a perfect square, such as 4, is rational; the root of any positive integer that is not a perfect square is an irrational number.

Search for the proof for the irrationality of the square root of 2. The same reasoning applies to any positive integer that is not a perfect square. In summary, the square root of any positive integer is either a whole number, or - as in this case - it is irrational.

The square root of any integer (except for a perfect square) is an irrational number. Other well-known irrational numbers are pi = 3.14159265... and e = 2.71828...

For a start, the square root of any integer is either an integer, or an irrational number.

Yes. In general, if an integer is not a perfect square, its square root is irrational.

A perfect square is a square of an integer (a whole number).

That term is not commonly used. A perfect square is simply the square of an integer. For example, 25 is the square of 5. Any positive number is the square of some number, but that number is usually irrational. For example, 2 is the square of the square root of 2 - approximately 1.4142136.That term is not commonly used.
