Question

What is the magnitude of -10 + 24i?

this is for a unit over complex numbers on a p e x​

Answer 1

The magnitude of the number is of 26.

Explanation:

Magnitude of a complex number:

A complex number has the following format: a + bi

In which a is the real coefficient and b is the imaginary coefficient.

The magnitude of the number is:

`√(a^2+b^2)`

What is the magnitude of -10 + 24i?

For this number, a = -10, b = 24. So

`√(a^2+b^2) = √((-10)^2+24^2) = √(676) = 26`

The magnitude of the number is of 26.
