f(3) = ...
​

Answer 1

SOAL 1

___________________________________________

f(a) = 5a² + 4(a!)²

___________________________________________

f(3) = 5(3²) + 4(3!)²

f(3) = 5(3.3) + 4(3.2.1)²

f(3) = 5(3.3) + 4(6.1)²

f(3) = 5(9) + 4(6)²

f(3) = 5(9) + 4(6.6)

f(3) = 5(9) + 4(36)

f(3) = 45 + 144

f(3) = 189

[ Soal ]

f(a) = 5a² + 4(a!)²

f(3) = ...

__________________

f(a) = 5a² + 4(a!)²

f(3) = ...

• f(3) = 5a² + 4(a!)²
• f(3) = 5(3²) + 4(3!²)
• f(3) = (5 × (3 × 3 ) + ( 4 × ( 3 × 2× 1²)
• f(3) = ( 5 × 9 ) + ( 4 × (6²)
• f(3) = ( 45 ) + ( 4 × ( 6 × 6 )
• f(3) = ( 45 + ( 4 × 36 )
• f(3) = ( 45 + 144 )
• f(3) = 189

Kesimpulan ←

• Maka, Hasil dari f(3) = 189
