Calculate the real part, the imaginary part, and the absolute value of the following expression:
i * [(1+2i)(5-3i)+3i/(1+i)].
So I did the math out this way:
i * [(4+21i)/(1+i)] = (4i-21)/(1+i)
Is this correct and what do you call the imaginary part and the real part if a denominator exists with an imaginary i?
Thanks for any help.
