arg(-2-i) = sqrt[22 + 12] = sqrt(5)
This is a complex number, not an algebraic expression. The letter i represents the imaginary unit (which is equal to sqrt(-1)). Graphiclly, with real numbers on a horizontal axis, and imaginary numbers on a vertical axis, this means starting at the origin, go to the left 5 units, and then go down 12 units.
9 to 12 is the ratio. BUT, if you simplify it (divide them both by the same number which makes both of them come out to a whole number) it's 3 to 4
To simplify 158/12, divide 158 by 12. The answer is 13 remainder 2. 13 is a whole number. Now, pit the 2 over 12. It is 2/12, but it needs to be simplified, so divide the denominator and numerator by 2. The answer is 1/6. Put it with the 13 and the final answer is 13 1/6.
It is 5 over 12.
-12 = 4 x 3 x -1 so sqrt = 2i root 3
sqrt(-12/4) = sqrt(-3) = +/- i*sqrt(3) where i is the imaginary sqrt of -1.

- 24 sqrt(6) / 6 sqrt(12) = (-24/6) sqrt(6/12) = (-4) sqrt(1/2)
Factorise 12.Replace each pair appearing in this factorisation as by the same number outside the radical and then put everything under the radical sign. sqrt(12) = sqrt(2*2*3) = 2*sqrt(3)

sqrt(12) = sqrt(4*3) = sqrt(4)*sqrt(3) = 2*sqrt(3)
To find the square root of 12, you can simplify it by breaking it down into its prime factors. Since 12 can be expressed as (4 \times 3) (where 4 is a perfect square), the square root can be calculated as (\sqrt{12} = \sqrt{4 \times 3} = \sqrt{4} \times \sqrt{3} = 2\sqrt{3}). If you need a decimal approximation, (\sqrt{12} \approx 3.464).

The expression "radical -1728" refers to the square root of -1728, which is not a real number because you cannot take the square root of a negative number in the realm of real numbers. In the context of complex numbers, it can be expressed as ( \sqrt{-1728} = \sqrt{1728} i = 12\sqrt{12} i ). Cubing this value, ( (12\sqrt{12} i)^3 = 1728\sqrt{12^3} i^3 = -1728 \cdot 12\sqrt{12} = -20736\sqrt{12} ). Thus, the cube of the square root of -1728 is a complex number.
-6 +/- i*sqrt(139) where i is the imaginary square root of -1.
You can't simplify a number into a bigger number, stupid
