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))`

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)

The following steps are involved in finding the value of (97)^(2) by using a suitable identify . Arrange them in sequential order from the first to the last . (A) 10000 - 600 + 9 = 9409 (B) Using the identify (a - b)^(2) = a^(2) - 2ab + b^(2) , where a = 100 and b = 3. (C) (97)^(2) = (100 - 3)^(2) (D) (100-3)^(2) = (100)^(2) - 2 (100)(3) + 3^(2)
