Did I solve the absolute value right, when solving I used [tex]\sqrt{(5)^2+(0)^2}[/tex]
which I only got 5, but I feel like that felt a little too easy and wanted to make sure i answer this question right.

Answer:

(-5, 0)

|z| = 5

Step-by-step explanation:

Complex numbers can be represented on an Argand diagram.

The x-axis is called the real axis and the y-axis is called the imaginary axis.

The complex number  z = x + iy  is represented on the diagram by the point  P(x ,y), where x and y are Cartesian coordinates.

Therefore, the complex number z = -5 can be represented on the Argand diagram by the point:

  • (-5, 0)

The absolute value of a complex number is the magnitude of its corresponding vector.

For a complex number  z = x + iy,  the absolute value is given by:

[tex]|z|=\sqrt{x^2+y^2}[/tex]

Therefore, the absolute value of complex number z = -5 is:

[tex]\implies |z|=\sqrt{(-5)^2+(0)^2}[/tex]

[tex]\implies |z|=\sqrt{25+0}[/tex]

[tex]\implies |z|=\sqrt{25}[/tex]

[tex]\implies |z|=5[/tex]
