Question

How do you perform the indicated operations and write the answer in form a+bi where a and b are real numbers?

Answer 1

It's difficult to answer this question without seeing the "indicated operations" the form a+bi is a standard form for imaginary numbers so you might see 2+3i, you can add this to say 4+5i by adding the real numbers (2+4) and the imaginary numbers (3+5) to get 6+8i.  Hope that helps.
