Can someone please check to make sure I got this correct? I would appreciate if you showed your work so that I could compare wit
dmitriy555 [2]

Answer:

-4

Step-by-step explanation:

[√2(cos(3π/4) + i sin(3π/4))]⁴

(√2)⁴ (cos(3π/4) + i sin(3π/4))⁴

4 (cos(3π/4) + i sin(3π/4))⁴

Using De Moivre's Theorem:

4 (cos(4 × 3π/4) + i sin(4 × 3π/4))

4 (cos(3π) + i sin(3π))

3π on the unit circle is the same as π:

4 (cos(π) + i sin(π))

4 (-1 + i (0))

-4

The point 0,4 means that b will be equal to 4, as it’s the starting point. From there, if you go down 4 twice you have 2, and then -4.
