The following steps are involved in finding the value of `100 (3)/(4) xx 99(1)/(4)` by using appropriate identify . Arrange them in sequential order . (A) `(100 + (3)/(4)) (100 - (3)/(4)) = (100)^(2) - ((3)/(4))^(2) [ because (a + b) (a - b) = a^(2) - b^(2)]` (B) `10000 - (9)/(16) = 9999 + 1 - (9)/(16) = 9999 (7)/(16)` (C) `(100)^(2) - ((3)/(4))^(2) = 10000 - (9)/(16)` (D) `100 (3)/(4) xx 99 (1)/(4) = (100 + (3)/(4)) (100 - (3)/(4))`A.
