Q. ( spesial 700 jawaban ) f(x) = x³ + 54(x) – x!! f(7) = …..
Penjelasan dengan langkah-langkah:
f(x) = x³ + 54(x) – x!!
f(7) = 7³ + 54(7) – 7!!
f(7) = (7 × 7 × 7) + 54(7) – 7!!
f(7) = (49 × 7) + 54(7) – 7!!
f(7) = 343 + 54(7) – 7!!
f(7) = 343 + (54 × 7) – 7!!
f(7) = 343 + 378 – 7!!
f(7) = 343 + 378 – (7 × 5 × 3 × 1)
f(7) = 343 + 378 – (35 × 3 × 1)
f(7) = 343 + 378 – 105
f(7) = 721 – 105
f(7) = 616
f(x) = x³ + 54(x) – x!!
f(7) = 7³ + 54(7) – 7!!
f(7) = (( 7 × 7 ) × 7 )) + ( 54 × 7 ) – ( 7 × 5 × 3 × 1 )
f(7) = ( 49 × 7 ) + 378 – ( 35 × 3 )
f(7) = 343 + 378 – 105
f(7) = 721 – 105
f(7) = 616
