PLS I REALLY NEED HELP!!!! I have no idea what I’m doing even though I got the answer pls!! BRAINLY AND 50 pointd

Answer:
I think you're doing one of these
√a square root √a ⋅ √a = a √9 = ±3
3√a cube root 3√a ⋅ 3√a ⋅ 3√a = a 3√8 = 2
4√a fourth root 4√a ⋅ 4√a ⋅ 4√a ⋅ 4√a = a 4√16 = ±2
n√a n-th root (radical) n/a for n=3, n√8 = 2
well let me know :)
