1-A) Express the result of the following complex number expressions in both rectangular ( Re+j Im) and polar/exponential (de) form. Note: you must write out the evaluation steps; don't simply write the answers. (You may perform the evaluation in either rectangular and/or polar form. Be sure to fully evaluate the resulting expressions.) (a) 7-j5 (b) -3 (c) (3-23) (d) -7j (e) (1)(4+3j)(5+27) (7-3j)(7-5j) (h) ((3j)+7j+9) (j) ((53)-(8j+3)) (7-51) (2+31)
