No.
The opposite (or inverse function) of the square root would be the square.

9 is the square ROOT of 81. Calculating a square root is the inverse operation of squaring a number.
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.
The inverse operation of taking the square root is to calculate the square.
Square root is the inverse operation of a square.
No.
The opposite (or inverse function) of the square root would be the square.
XX or X*X, can be written as X squared. The inverse of a function "sort of cancels it out". I know the inverse of a square is the square root. Since we need the inverse of X squared, it's inverse is the square root of X. sqrt(x)
The square of the square root of 36. Which can also be stated as the square of 6.

The inverse operation is to take a square root.
y = x2 where the domain is the set of real numbers does not have an inverse, because the square root function is a one-two-two mapping (except at 0). Any polynomial with more than one root, over the reals, has no inverse. y = 1/x has no inverse across 0. But it is possible to define the domain so that each of these functions has an inverse. For example y = x2 where x is non-negative has the square root function as its inverse.
The inverse of x2 is x-2.
For the modulus, first square both coordinates. Then add the results and square-root that sum. For the angle, divide the y-coordinate by the x-coordinate, then find the inverse tangent (tan-1) of that number.
