its \[-8\]

Answer 5

say -8 is x so (-8)^20 = x^20 therefore the 20th root of x^20 = x which is -8

Answer 6

I am not too sure but i somehow think it is +8 and not -8 bcoz say you take square root of(-8)^2 the root will be +8 and not -8 it should be applicable here also so i think it is +8 not -8.
(sqrt(x^2)=|x|)

Answer 7

Answer 8

20 root of -8 results in a complex number.
