Is the square root of negative 121 rational irrational or a real number?

Answer 1

Rational

Answer 2

The square root of -121 is imaginary. It has value of i11.

It is not rational, irrational, nor real. The coefficient of i, 11, is real and rational, but the result of multiplying i by 11 is imaginary.

Now, The Coefficient of (i11) is a complex number, because when dealing with i, the true form is the square root of -1, and so this also means that you still have 2 answers, positive and negative i11, and so the square root of -121 is imaginary, or complex rational number. But, because it is complex, it is not truly rational, all this means is that you end up with aninteger in your complex answer. So, To answer your question, the answer is non of the above, just imaginary. and the value is plus or minus (i11).

Answer 3

The square root of a negative number is considered an imaginary number, denoted by "i" in mathematics. In this case, the square root of -121 is 11i, where i represents the imaginary unit. Therefore, the square root of -121 is an imaginary number, which is a subset of the complex numbers.
