Understanding Imaginary Numbers

In mathematics, the imaginary unit is denoted as 'i', and it is defined as the square root of -1. This concept is crucial because the square of any real number is always non-negative. Therefore, to handle square roots of negative numbers, mathematicians introduced the concept of imaginary numbers.

Definition of 'i'

  • i = āˆš(-1)
  • iĀ² = -1

Calculating āˆš(-4)

To find the square root of -4, we can express -4 as a product of 4 and -1.

āˆš(-4) = āˆš(4 * -1)

Using the property of square roots, we can separate the terms:

āˆš(4 * -1) = āˆš(4) * āˆš(-1)

We know that:

  • āˆš(4) = 2
  • āˆš(-1) = i

Therefore,

āˆš(-4) = 2i

Expressing the Solution

The square root of -4 is 2i, where 'i' is the imaginary unit. This result indicates that āˆš(-4) is not a real number but an imaginary number.
