## Why is i the square root of negative one?

Here, the term “imaginary” is used, because there is no real number having a negative square. There are two complex square roots of −1, namely +i and −i, just as there are two complex square roots of every real number other than zero (which has one double square root).

## What does 2i mean?

## What are the positive and negative square roots of 4?

It is called principal square root denoted by √a. √ is called the radical symbol or radix and in this example, the principal square root of 4 is 2 which is denoted by √4 = 2 because 22 = 2 • 2 = 4 and 2 are non-negative….Square Root From 1 to 50.NumberSquare Root Value21.41431.7324252.23646 more rows

## Is the square root of 15 a rational number?

15=3×5 has no square factors, so √15 cannot be simplified. It is not expressible as a rational number. It is an irrational number a little less than 4 .

## How do you simplify negative exponents?

Apply the Negative Exponent Rule. Negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents. Only move the negative exponents.

## Is square root of 16 a rational number?

Answer and Explanation: The square root of 16 is a rational number. The square root of 16 is 4, an integer.

## Are imaginary numbers positive or negative?

No, an imaginary number is not positive or negative. A positive number is greater than zero, and a negative number is less than zero; but “greater than” and “less than” don’t exist for Complex numbers, only for Real Numbers, and Imaginary numbers are always Complex numbers.

## What happens if a square root is negative?

The square root of minus one √(−1) is the “unit” Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √(−1) is i for imaginary.

## How do you simplify a negative square root?
