1.58800 - (1.5402 sqrt(-1))
1.6 - 1.5i is one approximation. Is it a good one? I don't know -- what you're asking for is extremely vague. Is this a homework problem? If so, what is the complete statement of the problem.
14+39i is another approximation
But NOT a very good one! dami, please tell us what the problem really is!
