Understanding Complex Numbers

As we explore the concept of square roots of -2, it is imperative to have an understanding of complex numbers. Complex numbers are expressed in the form 'a + bi', where 'a' and 'b' are real numbers, and 'i' represents the imaginary unit. The imaginary unit is a fundamental element of complex numbers and is defined as the square root of -1.

Introduction to Square Roots of Negative Numbers

Traditionally, square roots are calculated by finding the positive number that, when multiplied by itself, yields the given number. However, for negative numbers, we introduce the concept of imaginary numbers. A square root of a negative number can be expressed as a multiple of the imaginary unit.

Calculation of Square Root of -2

To calculate the square root of -2, we first write it as -1 x 2. Then, we take the square root of -1, which is the imaginary unit 'i,' and multiply it by the square root of 2. Therefore, the square root of -2 is equal to 'i√2.'
