What is the value of n for which square root of n be a rational number?
n is a square of a rational number. For example, 4 or 81, or 2.25 or 36/25.n is a square of a rational number. For example, 4 or 81, or 2.25 or 36/25.n is a square of a rational number. For example, 4 or 81, or 2.25 or 36/25.n is a square of a rational number. For example, 4 or 81, or 2.25 or 36/25.
Is the square root of 25 an irrational number?
No. The square root of 25 is 5. 5 is an integer. And all integers are considered a rational number because they can be displayed as a fraction with a denominator (bottom number) that does not equal 0.
Is the square root of 22 a rational number?
No, in fact unless an integer has an integral square root, the square root is always irrational. Note that some rational fractions can have rational square roots, though. Example: sqrt(4/9) = sqrt(4)/sqrt(9) = 2/3, which is rational. Or sqrt(9/16) = 3/4
Is the square root of 99 a rational number?
√99 = Square root of 99 = Irrational. Rational # are able to be expressed as the ratio of 2 integers. i.e. √25 = +5 5 = 5/1 = rational Irrational # can not be expressed as a ratio of 2 integers.
Is the square root of zero rational or irrational?
The square root of 0 = 0. Rational is defined as a value that can be expressed as a quotient of integers. For example, 0/1 = 0 and 0/2 = 0. Although 0/0 is undefined, the former examples are still true. Therefore, the square root of 0 is rational. For your knowledge, the square root of any number is rational, except for negative numbers, which are irrational. This is because two identical integers cannot be multiplied to produce a negative integer. For instance, the square root of 25 is 5 because 5x5 = 25. However, the square root of -25 has no real roots because neither -5x-5 nor 5x5 = -25.
