Dijawab:

f(x) = 5x - x!!!

f(20) = 5(20) - 20!!!

f(20) = ( 5 × 20 ) - 20!!!

f(20) = 100 - 20!!

f(20) = 100 - ( 20 × 17 × 14 × 11 × 8 × 5 × 2 )

f(20) = 100 - ( 340 × 14 × 11 × 8 × 5 × 2 )

f(20) = 100 - ( 4.760 × 11 × 8 × 5 × 2 )

f(20) = 100 - ( 52.360 × 8 × 5 × 2 )

f(20) = 100 - ( 418.880 × 5 × 2 )

f(20) = 100 - ( 2.094.400 × 2 )

f(20) = 100 - 4.188.800

f(20) = -4.188.700

Answer 2

• 20!!!

• 20 × 17 × 14 × 11 × 8 × 5 × 2 × 1

• 340 × 14 × 11 × 8 × 5 × 2 × 1

• 4.760 × 11 × 8 × 5 × 2 × 1

• 52.360 × 8 × 5 × 2 × 1

• 418.880 × 5 × 2 × 1

• 2.094.400 × 2 × 1

• 4.188.800 × 1

• 4.188.800

• f(x) = 5x - x!!!

• f(20 = 5(20) - 20!!!

• f(20) = 5(20) - 4.188.800

• f(20) = (5 × 20) - 4.188.800

• f(20) = 100 - 4.188.800

• f(20) = - 4.188.700

[ kesimpulan ]

f(x) = 5x - x!!!

f(20) = - 4.188.700
