There is no real answer. The square root of negative one is denoted i for imaginary.
The square root of any negative number will always be a complex number. The word 'complex' can be supplemented for the word 'imaginary' which is what they can sometimes be called. 'i' stands for imaginary and equals the square root of minus one. sq(-1) = i - (that is the basic fact) The imaginary numbers work in a quadratic fashion (x^2) so: sq(-1) = i sq(-4) = 2i sq(-9) = 3i (so it takes the positive form of the number and square roots it, then multiplies it by i) Example: sq(-2) = sq(2)x (i) = (1.4142 x i) = 1.4142i

In mathematics there are real and imaginary numbers. Real numbers include 55.7 as a tangible quantity, The imaginary and opposite number is (a negative or minus) -55.7.

It is 3 minus 2i
11 + 17i is an IMAGINARY number. . Its conjugate is 11 - 17i NB Note the change of sign only.
It would be 8 minus 9i or 8-9i
The idea here is to change the sign before the imaginary term. In this case, since there is a minus, you change it to a plus.
the conjugate 7-2i
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).

Multiply the numerator and denominator by the complex conjugate of the denominator ... [ root(2) minus i ]. This process is called 'rationalizing the denominator'.
The square root of negative one is an imaginary number, signified by the italic lower-case i.
