SQRT(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 , where Failed to parse (syntax error): {\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

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
