Given that  `(x + iy)^14 = a + ib`, where  `x, y, a, b ∈ R, \ (y - ix)^14`  for all values of `x` and `y` is equal to

1. `−a - ib`
2. `b - ia`
3. `−b + ia`
4. `−a + ib`
5. `b + ia`

Given that  `i^n = p`  and  `i^2 = −1`, then  `i^(2n + 3)`  in terms of `p` is equal to

1. `p^2 - i`
2. `p^2 + i`
3. `−p^2`
4. `−ip^2`
5. `ip^2`
