SQRT(n)

• $n$ is any positive number.

Description

• This function gives the square root of a positive real number.
• Squaring is the value that can be multiplied by itself to give the original number.
• The square root of a number is the inverse operation of squaring that number.
• The root of a number is an equal factor of the number.
• Every non-negative real number a has only one non-negative square root, called the principal square root, which is denoted by ${\sqrt {a}}$, where Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \sqrt} is called the radical sign or radix.
• Square roots of positive whole numbers that are not perfect squares are always irrational numbers.
• Numbers not expressible as a ratio of two integers .

    This function will give the result as NaN when n is a negative number.

Examples

1. =SQRT(0)=0
2. =SQRT(1)=1
3. =SQRT(136)= 11.661903789690601
4. =SQRT(ABS(-625))= 25
5. =1..10@SQRT

Syntax

It is the number for which you want the square root.

SQRT gives a positive square root.

If number is negative, SQRT gives ‘NaN‘ an error

 Consider n = 625 then

=SQRT(625) gives 25
