Assuming you mean 3x3: If you work with real numbers, anything under the square root sign must be non-negative, so if you solve the inequality:
3x3 >= 0
for x, you get all valid values of x for this function, in other words, the domain.

3x y^3
Square root of 3=1 so 1+4=5
it is greater than and equal to 3
The question is ambiguous. Do you mean √(24*x4) or √24*x4? √(3x) or √3*x? The answer to √(24*x4) / √(3x) = (8x3) = 2x*√(2x)
x2 + 3x + 3 = 0 doesn't factor neatly. Applying the quadratic formula we find two imaginary solutions: (-3 plus or minus the square root of -3) divided by 2x = -1.5 + 0.8660254037844386ix = -1.5 - 0.8660254037844386iwhere i is the square root of negative 1
