Final answer:
We need to apply complex number rules and exponents to evaluate expressions (a) i^(2-i) and (b) (((-1 - i)^(-3+4i)) / 4), instead of using quadratic formulas or vector algebra provided in the references.
Step-by-step explanation:
The student's question involves evaluating complex expressions and writing the answers in the form a + bi. However, the formulas provided in the reference material do not seem to directly relate to the student's question about complex numbers. To proceed with a correct answer, we would apply complex number rules and exponents to evaluate each part of the question.
For part (a), i^(2-i), we would simplify i^2 and then determine the effect of raising i to the power of -i. For part (b), ((-1 - i)^(-3+4i)) / 4, we would apply the rules of exponents for complex numbers, calculate the power of the complex number, and then divide by 4.
The student's question related to complex numbers does not seem to be accurately addressed by substituting values into the quadratic formula or vector algebra as mentioned in the reference material.
