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.
Well, honey, the square root of -81 is actually an imaginary number, not a real number. So, technically speaking, it's neither rational nor irrational. It's just hanging out in its own little imaginary world, causing trouble for those who dare to solve it.
Well, isn't that a happy little question! The square root of -81 is actually an imaginary number, because you can't find the square root of a negative number in the real number system. It's like painting a beautiful sky full of colors that don't exist in nature, but they sure do add some magic to the painting!
Oh, dude, the square root of -81 is actually an imaginary number because you can't take the square root of a negative number and get a real answer. So, technically, it's neither rational nor irrational, it's just hanging out in its own imaginary world, probably sipping on an imaginary latte or something. Like, it's cool, but it's not playing by the rules of the real number crew.
Since it is the square root of a negative number, it is actually imaginary, neither rational nor irrational. It is equal to 9i, or 9 times whatever the square root of negative one is.

What is the value of 'n' for which under root 'n' be a rational number is?
Oh, what a lovely question! You see, for the square root of 'n' to be a rational number, 'n' must be a perfect square. When 'n' is a perfect square, the square root of 'n' will be a whole number, which is a rational number. Just like painting happy little trees, mathematics can be a beautiful and harmonious world when we understand its patterns and shapes.
