i need help

Basically we need to know, “what is the domain of the question?”.
If the domain is the set of real numbers, then there is NO square root.
If the domain is the set of complex numbers, then the roots are \(\displaystyle \pm 14i\).
 
The answer is -14. The same rules apply if you're trying to find the square root of a negative number or a positive number. The only difference is the negative sign.

if what you said about the rules are true, then: -14*-14= -196. not exactly. remember a square root is to the half power, meaning the two multiplicands that make up your total should be identical.

if you think of a root as your divisor and your answer being equal then...

if i tried to divide -196 by +14 i should get +14 as my answer
-196/+14=-14 nope

now i will try to divide -196 by -14, then i should gget -14 as my answer
-196/-14=+14 neither divisor is equal to the answer.

are you SURE the problem is not stating the opposite of the square root 196?
 
no the anwser is just 14!

The anwser is 14 because 14 times 14 = 196

Please read the discussion above.

14<sup>2</sup> = 14 * 14 = 196 ≠ -196

(-14)<sup>2</sup> = (-14)*(-14) = 196 ≠ -196

-14<sup>2</sup> = -(14)*(14) = -196 but has little relationship to a square root.
