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`

Find the value of ( 2^-1 - 4^-1 )^2

The following steps are involved in finding the value of 10 (1)/(3) xx 9(2)/(3) by using an appropriate indentity . Arrange them in sequential order . (A) (10)^(2) - ((1)/(3))^(2) = 100 - (1)/(9) (B) 10(1)/(3) xx 9(2)/(3) = (10 + (1)/(3)) (10 - (1)/(3)) (C) (10 + (1)/(3)) (10 - (1)/(3)) = (10)^(2) - ((1)/(3))^(2) [because (a + b) (a -b) = (a^(2) - b^(2))] (D) 100 - (1)/(9) = 99 + 1 - (1)/(9) = 99(8)/(9)
