If 8a-64b-c = 24 cube root of abc is not equal to zero, then which of the following can be true? 1) 2 cube root of a - 4 cube root of b - cube root of c = 0 2) 2 cube root of a = 4 cube root of b = cube root of c. 3) a+b+c=0 4) a=b=c.

1) 2∛a - 4∛b - c = 0 is correct one
[if 2) is correct 2∛a = 4∛b = ∛c take each are equal to 1 so 1-1-1 = -1 which is ≠ 0]
[ 3 & 4 can't be the answers because a has 8 and b has 63. So when whatever value we give a, b and c answer will not be zero]
