It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).
The square root of -1 is the imaginary number i.So the square root of -4 = 2i
4 square root of -9 = 4 square root of (-1)(9) = 4 square root of (i29) = 4(3i) = 12i
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.
8 (positive or negative)
The square root of 64/4 = 4
The negative square root of 16 can be either +4 or -4 . Both are correct.
2 root 3 over 2, so square root of 3
There is no square root of negative 8, negative numbers can never be square rooted since no two of the same number can go into a negative number, for example 16's square root is 4 and -4 since 4x4=16 and -4x-4=16, but -16 doesn't have a square root since -4 just turns into a positive when multiplied to itself.
-16 i think
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.
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.
Positive 4 and Negative 4
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
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.
4 over square root of 16 simplifies to 1 !
the square root of (1/4) is 1/2
The negative square root of 16 is -4. It can be written as the ratio of 792 to -198, so it's rational.
no, it is actually not a real number. It falls under the category of a imaginary number which is the square root of -1 or as the variable i Because the square root of -4 is 2i because the square root of 4 is 2 and if you take i out it will maek it a positive so it goes like this -4 SR= 2i -9 square root= 3i and so on
The answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.
It is rational.
No, but it is imaginary: 2i.
