Answer 1

@jim_thompson5910

Answer 2

can you draw it out?

Answer 3

\[18-4i \]

Answer 4

@jim_thompson5910 its just the last step of the problem and rad 4 is 2 but im just not sure if you just mutiple it to the 18

Answer 5

it seems odd to me, but if it really is \(\Large 18-4i\sqrt{4}\)

then

\[\Large 18-4i\sqrt{4} = 18-4i*2 = 18-8i\]

Answer 6

but I think something is missing here because that was a bit too easy for this level of math

Answer 7

the whole problem is (10-rad -72) + (8+rad -8) but i just dont know what to do for the last step @jim_thompson5910
