Mathematics
1 answer:

Answer:

=\pm i\sqrt{66}

Step-by-step explanation:

So we have:

\pm\sqrt{-66}

This is the same as:

=\pm\sqrt{66\cdot-1}

Separate:

=\pm\sqrt{66}\cdot\sqrt{-1}

Replace the second term with i:

=\pm i\sqrt{66}

The square root of 66 cannot be simplified.

So, this is our answer :)

Find the absolute value of the complex number 5 - 4i.
Damm [24]
I answered a similar question for someone else. The absolute value of a complex number is called the modulus. This represents the DISTANCE to the origin from the point on the imaginary + real plane. 
the real horizontal distance is 5 and the imaginary vertical distance is in this case 4 (from -4i) the distance is 4. So to figure out this just use the Pythagorean theorem.
5^2 + (4)^2 = c^2 
25 +16 = c^2 
c^2 = 41c = 6.4 So option D.
