It is just a notation, used to make our calculations easier. Square root of -1 is undefined.
Mathematicians decided that, since the square root of a negative number does not exist, they would use the first letter of "imaginary" to represent this "value".
Finding the square root of a number is the same as saying: What number multiplied by itself is equal to the number. In this instance, the square root of 1 is equal to 1 x 1. Therefore, the square root of 1 is 1.Similarly, the cube root of 1 is also 1 (1 x 1 x 1 = 1)
You would get (i square root 2) because you can not square root a negative number, the answer is imaginary. Tmdkiller: Square root is NOT applicable to any Negative numbers eg -1 ,-2,-3 etc You would get an "Error 2" on a scientific Calculator anyway. =) editted by razakhan squre root of -2 is 2i (where "i" is "iota" represents imaginary or complex number......
Rounded to two decimal places, the square root of 3.2 is equal to 1.79.Expressed as a surd, the square root of 3.2 is equal to (4 (sqrt 5)) / 5.
8
square root of -1
Square Root of 1.6 is not equal to 1.6 Example- Square Root of 1 is not equal to 1.
Mathematicians decided that, since the square root of a negative number does not exist, they would use the first letter of "imaginary" to represent this "value".
The square root of 12 is: ± 3.464102
-1
sin-30 = (-1) x 1/(square root of 2) -sin30 = -(1/square root of 2) They are equal
The square of negative iota will be the same as the square of positive iota (i.e. -1) because when a negative number is multiplied by a negative number, the answer is positive.
The square root of -64 is 8i. ' i ' is the unit imaginary number, equal to the square root of -1, or 1 at an angle of pi/2.
The square root of minus 8 is equal to the square root of 8 times the square root of minus 1, or 2.8284i.
Finding the square root of a number is the same as saying: What number multiplied by itself is equal to the number. In this instance, the square root of 1 is equal to 1 x 1. Therefore, the square root of 1 is 1.Similarly, the cube root of 1 is also 1 (1 x 1 x 1 = 1)
The complex pair ± 2.4495i (approx) where i is the imaginary square root of -1.
The square root of 1/36 is equal to 1/sqrt(36) - that is, 1/6, or one sixth.
