Answer 1

Penjelasan dengan langkah-langkah:

f (×) = 12x × 10!! + 7x

f (7) = 12(7) × (10×8×6×4×2) + 7(7)

f (7) = ( 12×7) × (80×6×4×2) + (7×7)

f (7) = 84 × (480×4×2) + ( 49 )

f (7) = 84 × (1,920×2) + 49

f (7) = 84 × ( 3,840) + 49

f (7) = 84 × 3,840 + 49

f (7) = 322,560 + 49

f (7) = 322,609 ✔
