Answer :

(i)


(4x)2 + 2 (4x) (3) + 32


= (4x + 3)2


Putting x =


= [4 () + 3]2


= (7 + 3)2


= 100


(ii)


(8x)2 + 2 (8x) (9y) + (9y)2


= (8x + 9y)2


Putting x = 11 and y =


= [8 (11) + 9 ()]2


= (88 + 12)2


= (100)2


= 10000


(iii)


(9x)2 + (4y)2 – 2 (9x) (4y)


= (9x – 4y)2


Putting x = and y =


= [9 () – 4 ()]2


= (6 – 3)2


= 32


= 9
