A. The cube roots of -27 are 3

B. The fourth roots of 81 are 3
C. 3√-1000=-√1000
D. 4√-16=-4√16

Which of the following statements are true
1. B and C only
2. A, B and C only
3. A,B,C and D
4. Some other combination of A, B, C and D

None is true as things are written

∛-27 = -3 and two complex roots
∜81 = ±3 and two complex roots
3√-1000 = 30√-10 = 30√10 i
4√-16 = 4*4i = 16i
