How do you deal with negative square root

[From: ] [author: ] [Date: 11-08-18] [Hit: ]
or you could write no real solutions-if the given is in the negative form then automatically you will write i which means imaginary because An imaginary number is a number with square that is negative. When any real number is squared, the result is never negative. Imaginary numbers have the form biwhere bis a non-zero real number and i is the imaginary unit, defined such that i2 = −1-The square root of a negative number is only invalid when you isolate your mathematics to the real number system. On a complex number system,......
If you found the answer to an equation in the form of a negative square root, (e.g. sqrt -4), what do you state (in an exam paper) to show that it is not a valid value?

Thanks!

-
sqrt -4 could be shown as 4i
i being the imaginary number sqrt -1

or you could write "no real solutions"

if the given is in the negative form then automatically you will write " i " which means imaginary because An imaginary number is a number with square that is negative. When any real number is squared, the result is never negative. Imaginary numbers have the form bi where b is a non-zero real number and i is the imaginary unit, defined such that i 2 = −1

The square root of a negative number is only invalid when you isolate your mathematics to the real number system. On a complex number system, your answer is equivalent to the following.

i = √(-1)

√(-4) * i = i√(4) = ±2i

-
At that point, you should have been trained on imaginary numbers based on the square root of -1, and how to use them. Look it up.

-
negative square root will have a imaginary answer. like sq.root(-1)=i,
sq.root(-4)=sq.root(-1)sq.root(4)=2i.
good luck!!!

-
Since you haven't yet learned about imaginary numbers,
then simply state that there is no real solution.

-
well the value does exist its just that it is imaginary
by the way the value is + or -2i

-
√-4 = 2i

2i is an imaginary or complex number. It is not a real number solution.

-
imaginary value....i = sguare root of (-1); i*2= -1;

-
Its imaginary.

Here's what you say:

"No Real Solutions"
