yes
Yes, if your equation is f(x) = sqrt5(x). The square root is also a function itself, if that's what you mean.
Let's illustrate with an example. The square function takes a number as its input, and returns the square of a number. The opposite (inverse) function is the square root (input: any non-negative number; output: the square root). For example, the square of 3 is 9; the square root of 9 is 3. The idea, then, is that if you apply first a function, then its inverse, you get the original number back.
Standard deviation = square root of variance.
Answer: The difference between the square root of x and squared is either x or -x. Answer: The square root is the inverse function of the square function. That means that it's basically the opposite. Asking for the square root of "x" is like asking "what number must I square to get 'x'".
The standard deviation of a normal deviation is the square root of the mean, also the square root of the variance.
It is the "square root." This is the opposite function (n1/2) of the square (n2).
yes
The standard form of a complex number is a+bi. So the standard form of the negative square root of 5i is 0-√(5i).
The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.

Standard deviation = square root of variance.
This is typically done by importing math.h, and calling the sqrt function.
Math.sqrt(number) function is used to find the square root of a number.. try it
