A rational number can always be written as (one whole number) divided by (another whole number). That's not only a characteristic of a rational number, it's the definition of one.
The square root of any positive integer can only be a WHOLE NUMBER or IRRATIONAL, so the square root of 7 is irrational.On the other hand, the sum of a rational and an irrational number is always irrational.
Irrational.
It is a real number, a rational number, an integer.
It can be written as a fraction, so it is rational. It is not an integer, whole number or irrational.
Yes...because a whole number does not have an irrational part to it.
A perfect square is a rational number equal to the square of a whole number.
No, it may be not even a rational number. Square root of 2 is 1,414213562... for example.
If the whole number is a perfect square, its square root is rational. If not, it's not.
When the whole number is a perfect square, ie it is a whole number squared.
It is always rational.
The square root of 25 is 5, which is a whole number, an integer, a natural number and a rational number.
A perfect square.
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.
No. In fact, no odd integer is irrational. They are all rational.
The √49 is 7. It is a rational number.
The square root of four is a real number because it is a non-negative number that can be expressed on the number line. It is also a rational number because it can be expressed as the fraction 2/1. In fact, it is both a real number and a rational number, as all rational numbers are also real numbers.
