what is solution to this complex number exponential: (5 - 3i)^7. Any ideas? Give as many forms as possible, i.e., algebraic, exponential, polar...etc. Thank you very much.

I would start by doing a binomial expansion on it. Have you done that yet?
OR you could just put it straight into the web2 calculator.
(5 - 3i)^7 = -183 640+137 112i

z = (5 - 3i)^7
Algebraic form:
z = -183640+137112i
Exponential form:
z = 229179.733275 × ei 143°15'13″
Trigonometric form:
z = 229179.733275 × (cos 143°15'13″ + i sin 143°15'13″)
Polar form:
r = |z| = 229179.73328
φ = arg z = 143.2537° = 143°15'13″ = 0.79585π
