I think it would be 0.72 i don't really know sorry just trying to help :) have a cool day
you need to distribute -1 into the second parenthesis as follows:
(1+6i)-(7+3i) = 1 + 6i - 7 - 3i
then combine like terms:
(1-7) + (6i - 3i)
=
-6 + 3i
Done
(1+6i)-(7+3i) = 1 + 6i - 7 - 3i
then combine like terms:
(1-7) + (6i - 3i)
=
-6 + 3i
Done
I hope that helps!
