Now, required square of 9 = 9 x 9 = 81.
Given Exp = 3 2 6 - 3 × 6 + 3 6 + 3 - 4 3 6 - 2 × 6 + 2 6 + 2 - 6 2 2 - 3
= 3 2 ( 6 + 3 ) 6 - 3 - 4 3 ( 6 + 2 ) 6 - 2 + 3 3 - 2 × 3 + 2 3 + 2
= 2 6 + 3 - 3 6 + 2 + 3 3 + 2
= 12 + 6 - 18 - 6 + 3 3 + 3 2
= 5 3
By simplifying, we get 4/3
( 0 . 75 ) 3 1 - 0 . 75 + 0 . 75 + ( 0 . 75 ) 2 + 1 = ( 0 . 75 ) 3 + ( 1 - 0 . 75 ) ( 1 ) 2 + ( 0 . 75 ) 2 + 1 × 0 . 75 1 - 0 . 75
= ( 0 . 75 ) 3 + ( 1 ) 3 - ( 0 . 75 ) 3 1 - 0 . 75 = 1 0 . 25 = 4 = 2
