D{-10;-24},|d|=

To find the magnitude (or absolute value) of a complex number, you can use the formula:

|d| = √(Re(d)^2 + Im(d)^2)

Where d is a complex number, Re(d) is the real part of d, and Im(d) is the imaginary part of d.

In this case, the complex number is d = -10 - 24i.

So, the real part of d is Re(d) = -10 and the imaginary part of d is Im(d) = -24.

Using the formula, we have:

|d| = √((-10)^2 + (-24)^2) = √(100 + 576) = √676 = 26

Therefore, the magnitude of d is |d| = 26.
