4 square root of -9 = 4 square root of (-1)(9) = 4 square root of (i29) = 4(3i) = 12i

The negative square root of 16 can be either +4 or -4 . Both are correct.

-4

-28(square root)10

It is not possible for a negative number to have a square root. Any square root is the number that, when you multiply it by ITSELF it will equal the number you are square rooting. Example: The square root of 4 is 2. 2 times itself(2x2) is 4. Negative numbers are imposable to square root because the square root cannot be multiplied by its opposite ( i.e. -2 times 2 or 4 times -4), it must be multiplied by itself. Any positive multiplied by a positive is a positive, and any negative multiplied by a negative is a positive. So any number times ITSELF will always be a positive. ( i.e. -4 time -4 is 16 as 4 times 4 is also sixteen.) If a squared square root is always positive then a negative number cannot have a square root. It's imposable.* * * * *True for basic mathematics but not so for more advanced mathematics. There is a whole area of mathematics called complex mathematics which is based on the square root of negative numbers. The square root of -1 is defined as i.

It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).

The negative square root of 16 can be either +4 or -4 . Both are correct.

-4

it is impossible to get the square root of a negative, since the definition of a square root is something times itself. example: the square root of 16 is 4 because 4 x 4 = 16. and a negative times a negative is a positive, so the square root of a negative is impossible. however, you can do the square root of 121 (which is 11) and make the 11 a negative. 11 x 11 = 121 and -11 x -11 = 121 but you could make 11 negative after the fact, if that is what you wanted to do.

The square root of a negative real number is an imaginary number.We know square root is defined only for positive numbers.For example,1) Find the square root of (-1)It is imaginary. We say that square root of (-1) is i.In fact they are not real numbers.2) Find the square root of (-4)-4 can be written as (-1)(4)Square root of 4 is 2 and square root of (-1) is iSo, the square root of -4 is 2i.Similarly, we can find the square root of other negative numbers also.Source: www.icoachmath.comAn imaginary number is defined to handle square roots of negative numbers. The imaginary unit i is defined as the 'positive' square root of -1.

Every number has two square roots ... a positive one and a negative one. Example: +2 and -2 are both square roots of 4, because when you multiply either of them by itself, the answer is 4. The positive square root of a number is the square root that's not negative. The non-negative square root of a number is the positive one.

Positive 4 and Negative 4

The negative square root of 16 is -4. It can be written as the ratio of 792 to -198, so it's rational.
