What is the square root of 1

Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbersusing addition and multiplication. Here, the term "imaginary" is used because there is no real number having a what is the square root of 1 square. In contexts in which use of the letter i is ambiguous or problematic, the letter j is sometimes used instead.

The square root of 1 refers to the value which when multiplied by itself gives the result as 1. For 1, its square root can be either 1 or -1 as both 1 multiplied by 1 and -1 multiplied by -1 gives the result as 1. In general, every number has two square roots, i. In general, when talking about square roots , only the positive square root is considered i. As 1 is a real number and the square of any number is positive, we can assume that the square root of 1 is 1 itself.
