no. irrational numbers are square roots of numbers that aren't square, pi, and some other numbers. irrational means it never ends.

Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.

In mathematics, there is a distinction between real numbers and imaginary numbers. There is a number known as i which means, the square root of minus one. Since any number that we know of will produce a positive result when multiplied by itself, there would seem to be no such thing as the square root of minus one, however, the concept is useful for certain purposes, nonetheless, and it is therefore known as an imaginary number. Any multiple of i is also an imaginary number (such as 67i and so forth). So, some square roots are real numbers, and some are imaginary. Both types can be called square roots.

The square roots of some numbers are rational: eg sqrt(4) = 2, sqrt(0.04) = 0.2, sqrt(400) = 20 The square roots of some numbers are irrational eg sqrt(2) = 1.414 (approx), sqrt(0.02) = 0.1414 (approx), sqrt(200) = 14.14 (approx) The square roots of negative numbers are neither rational nor irrational, but imaginary.

Because some of them are squares of rational numbers. So their square roots are the rational numbers.Thus if x is rational, then the square roots of x2, which are -x and +x are both rational.

Some square roots of whole numbers are integers, some of them are irrational numbers. The square root of four for instance is a rational number, 2. The square root of two however is an irrational number, approximately 1.414211356.

Not always as for instance the square root of 16 is 4 which is a rational number but the square root of 2 is an irrational number.

They are called irrational numbers; numbers that can be expressed as a ratio of integers are called rational numbers. Some common irrational numbers are pi (3.14159...) and the square root of two.

There is no special symbol for an irrational number. However, it is known that many square roots, cubic roots, etc., as well as some special numbers such as pi and e, are irrational.
