1. Estimate given expression j^-10.
2. Do indicated operation and state result in rectangular and polar forms, (6.59e^1.64j)^2
3. Change given number to polar form and then divide. State result in rectangular form and polar form. Check answer by diving original number in rectangular form, -3/2-5j.
4. For given system, multiply or divide every term of both equation by the number selected through inspection in order to make coefficient easier to work with. Solve system using suiatble algebraic method. 40s - 30t =80, 20s - 40t = -50.
