is that 12 or i2?

Answer 2

This problem seems incomplete. Can you clarify?

Answer 3

7 and 12 are one problem and 3i +9 are another problem

Answer 4

Sorry the problem is above my pay grade lol, don't understand the problem, conjugates are used with radicals and complex numbers to simplify. Hopefully someone will enlighten you (and myself). You may want to submit the problem again so it doesn't indicate "replies"

Answer 5

ok, no problem
