The concept is fundamental to geometry. A square, with sides of one unit, has a diagonal of length = sqrt(2).
Pythagoras's theorem appears all over the place. If you have a doorway that is X units wide and Y units tall, then the widest object you can take through it is sqrt(X2 + Y2) units.
On a Cartesian plane (or even city blocks) the distance (as the crow flies) between two points that are X blocks apart North-to-South and Y blocks East-to-West is also sqrt(X2 + Y2) times the block size.

What are the six basic functions in math?
Constant, Identitiy f, Absolute, Square root, square, and Cube root function * * * * * There are four basic functions and these are addition, subtraction, multiplication and division.
How do you find square root of square 21?
The square root and square functions are inverse of one another EXCEPT that square root is not really a function: it is a 1-to-many mapping. So sqrt(square(21)) = sqrt(441) = ±21
How do you plot pi and the square root of two on a timeline?
pi and the square root of two are mathematical constants. They are not functions of time and so cannot be plotted on a timeline!
When will you use Square root functions in real life?
The diameter of a rectangular area is the square root of the length squared plus the width squared. D = √(L²+W²).
What are some of the irrational numbers?
Square root of 2, square root of 3, square root of 5... actually the square root of any number that is not a perfect square.Cubic root of 2, cubic root of 3... again, the cubic root of any number that is not a perfect cube.Pi (about 3.1416)e (about 2.718)Trigonometric functions, for most values of the domainLogarithm and antilogarithms, for most values of the domainMost expressions that include any of the above.

What is the inverse operation of exponential functions?
Square roots? for example, 5 to the 2 is the square root of 5. 6 to the 3 is the cubed root of 6.
What are characteristics of square root functions?
There are two square root functions from the non-negative real numbers to either the non-negative real numbers (Quadrant I) or to the non-positive real numbers (Quadrant IV). The two functions are symmetrical about the horizontal axis.
What is the relationship between squared and square root?
They are inverse functions of each other.

How can a new function be created by composing two existing functions?
You use the output of the first function as the input of the second function. For example, if your functions are sin() (the sine function) and root() (the square root function), you can combine them as:sin(root(x)) or: root(sin(x))
What basic functions have no x-intercept?
Those that have a negative number under the square root. It then has no x-intercept.
