The square root of 0.144 is an irrational number
The square root of 12 is an irrational number
No.
No. 81 is a rational number. An irrational number is a number with an endless amount of digits like pi or the square root of 2.
No because the square root of 81 is 9 which is a rational number
No. The square root of 81/(-3) is rational. The square root of [81/(-3)] is imaginary (a kind of complex number).
no. it is 9
The square root of 81 is 9, which is a whole number. Since all whole numbers are considered rational numbers (as they can be expressed as a fraction with a denominator of 1), the square root of 81 is rational.
No, the square root of an irrational number is not always rational. In fact, the square root of an irrational number is typically also irrational. For example, the square root of 2, which is an irrational number, is itself irrational. However, there are exceptions, such as the square root of a perfect square of an irrational number, which can be rational.
No, -81 is not an irrational number because it can be represented in the form x/y = -81
The square root of -81 is an imaginary number, specifically 9i, where i represents the imaginary unit equal to the square root of -1. Since the square root of -81 does not result in a real number, it is considered irrational. Rational numbers are those that can be expressed as a ratio of two integers, whereas irrational numbers cannot be expressed in this form.
The square root of 94 is an irrational number
Yes. For example, the square root of 3 (an irrational number) times the square root of 2(an irrational number) gets you the square root of 6(an irrational number)
The square root of 27 is an irrational number
