Question

What are the real and imaginary parts of the complex number?

Answer 1

Real part 2 , imaginary part -5i

Explanation:

Complex numbers written like this are in the rectangular form.

The general definition is `a + bi`

Where `a` and `b` are real numbers and `i` is the imaginary unit

`i = sqrt(-1)`

If we have `a + 0i` we have a real number.

If we have `0 + bi` we have a pure imaginary number.

If we have `a + bi`
`a != 0, b != 0` then we have a complex number with a real part and an imaginary part. The real part is `a` the imaginary part is `bi`

So `2 - 5i`

The real part is 2, the imaginary part is `-5i`
