- Evaluate the following complex numbers. Express your answers in rectangular form and Euler form. Show your detailed solution. 1. (-7+ 24i)²(5 – 5i) Ans. -955 – 4315i, 4419. 42 e-i 102.48°arrow_forwardSimplify. (2 (cos+ i sin ))³ Enter the answer in the standard form of a complex number with the real part in the first answer box and the imaginary part in the second answer box. If the complex number has no real term, enter "0" in the first answer box. If the complex number has no imaginary term, enter "0" in the second answer box. Express your answer to two decimal points, if appropriate. iarrow_forwardRepresent the following complex number in polar (R∠φ) format:−5−12?arrow_forward
- Given the following complex numbers, find: x = 4 + 5i y = 6 - 3i z = 4 + 4i a. the product of x* and z b. the quotient of the xy divided by square root of x.arrow_forwardDirections: Set your calculators on radians at this point. Do not round off during intermediate solutions. Use 3 decimal places (if applicable) in your final answer. For complex numbers, use this format (a+jb): 1. No spaces in between! 2. Use 'j' as the imaginary number 3. Use 3 decimal places (if applicable) for Real and Imaginary parts. Ex. 1.247+j0.557, 1.5-j0.5 Calculate the 3-point DFT of the given sequence: x(n) = [10 -1]arrow_forwardFor-343, (a) find all cube roots of the complex number. Write answers in trigonometric form.
