Prove that sum of cube roots of unity is zero.

To find roots of the equation x3 - 1 = 0 x3 - 1 = 0 (x - 1)(x2 + x + 1) = 0 Since x3 - 1 = 0 is a polynomial equation of degree 3, it will have three roots. We can see that one of the roots is 1.

If n is an odd integer, which of the following must be an odd integer? (A) n - 1 (B) n + 1 (C) 2n (D) 3n + 1 (E) 4n + 1

n is odd, then n - 1, n + 1, 2n, 3n + 1 are even. n is odd, then 4n is even. Hence, 4n + 1 is odd. So correct option is (E)

A 19-liter mixture consists by volume of 1 part juice to 18 parts water. If x liters of juice and y liters of water are added to this mixture to make a 54-liter mixture consisting by volume of 1 part juice to 2 parts water, what is the value of x? (A) 17 (B) 18 (C) 27 (D) 35

x + y = 54 54-liter mixture consisting by volume of 1 part juice to 2 parts water, this means there is 18 liter juice and 36 liter water in the mixture. Hence, x = 18
