No 162 × 25x - 16x = = ( 62 × 25 - 16 )x = ( 1.550 - 16 )x = 1.534x No 2 f(x) = 6x + x!! + x² f(13) = 6(13) + 13!! + 13^2 f(13) = 78 + ( 13 × 11 × 9 × 7 × 5 × 3 ) + ( 13 × 13 ) f(13) = 78 + 135.135 + 169 f(13) = 135.213 + 169 f(13) = 135.382 No 3 6! + 10!! - 3! + 7! = ......= ( 6.5.4.3.2.1 ) + ( 10.8.6.4.2 ) - ( 3.2.1) + ( 7.6.5.4.3.2.1 ) = 720 + 3.840 - 6 + 5.040 = 4.560 - 6 + 5.040 = 4.553 + 5.040= 9.594
