Question

How do you find `abs(-2i )`?

Answer 1

`abs(-2i)=color(green)(2)`

Explanation:

The absolute value of a complex number is its distance from the origin in the complex plane.

`-2i` is a point on the complex plane `2` units below the Real axis and on the Imaginary axis (its Real component is `0`).

Therefore its distance from the origin is `2`
