18 i
that should be a lower case i to represent the imaginary unit. Square roots of negatives are factored into (-1) x a 2nd positive factor ... (-1) x 324 in this problem.
the square root of (-1) is defined as the imaginary unit represented by i
306
- (400^.5) = -(20) = -20 you just do the square root of the number, and attach the negative in front. and if you ever include the negative inside the square root, you'd have to deal with i, which is an imaginary number that signifies the square root of negative 1.
The first perfect square which is greater than 300 is 324.
Negative 18 times negative 18 equals positive 324.
The square root is 238198.4 approx.
The negative square root of 324 is -18.

4x-x^2 \ 2-square root 2 multiply 2+squre root x\ 2+squreroot x = 4x-x^2 (2+squre root x) \ 4_x = x(4-x) (2+squre root x) \ 4-x we will cancel the (4-x) so it will be x(2+squre root x) = (0) (2+squre root 0) =0
The first perfect square which is greater than 300 is 324.
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......
Negative 18 times negative 18 equals positive 324.
Square root of 324 is 18 or 3 times the square root of 2
The square root is 238198.4 approx.
If you mean the square root of 225 then it is 15
