Answer:

#### Explanation:

The magnitude of a value is the absolute value.

The absolute value of any number is its distance from 0.

In this case, we have a complex number with real value of 3 and imaginary value of -7. In the complex number plane, the "x-axis" is the real axis while the "y-axis" is the imaginary axis.

Therefore, to find the magnitude of

which does not have any squares, so this is our answer.
