Question

If the constant on the right side is not a perfect square, the answers will be

rational
or
irrational

Answer 1

Irrational number

Explanation:

A square root is written with a radical symbol
`\sqrt` and the number or expression inside the symbol, is called the radicand.

`\sqrt b`

There is two roots of a positive number and to indicate that we want both the positive and the negative square root of a radicand we put the symbol ± in front of the root. For example,

`\pm \sqrt {16}=\pm 4`

If the square root of an integer is another integer then the square is called a perfect square.

If the radicand or the right side is not a perfect square i.e. the square root is not a whole number than you have to approximate the square root .

`\sqrt 3=1.732..`

The square roots of numbers that are not a perfect square are members of the irrational numbers.
