Step-by-step explanation:

We want to find the value of:

$\displaystyle |6-3i|$

Recall that given a complex number z in the form:

z=a+bi

The absolute value of z will be given by:

$\displaystyle |z| = \sqrt{a^2+b^2}$

We have the complex number:

6-3i

Thus, a = 6 and b = -3.

Then its absolute value will be:

$|6-3i|=\sqrt{(6)^2+(-3)^2}$

Evaluate:

$\displaystyle |6-3i|= \sqrt{36+9}=\sqrt{45}=3\sqrt{5}$

Hence, our answer is B.
