The following steps are involved in finding the value of `a^(4) + (1)/(a^(4))` when `a + (1)/(a) = 1` . Arrange them in sequential order from the first to the last . (A) `a^(2) + (1)/(a^(2)) + 2 = 1 implies a^(2) + (1)/(a^(2)) = -1` (B) `(a^(2))^(2) + ((1)/(a^(2))^(2))^(2) = 1^(2)` (C) `(a + (1)/(a))^(2) = 1^(2)` (D) `(a^(2) + (1)/(a^(2)))^(2) = (-1)^(2)` E `a^(4) + (1)/(a^(4)) = -1`A.
