Answer 1

f(x) = 20x × 4³

f(5) = 20(5) × ( 4 × 4 × 4 )

f(5) = 100 × ( 16 × 4 )

f (5) = 100 × 64

f(5) = 6.400

Answer 2

6.400

Penjelasan dengan langkah-langkah:

Diketahui:

• x = 5

Ditanya:

• f(x) = 20(x) × 4³ = ...?

Jawab:

• f(x) = 20(5) × 4³
• f(5) = 20(5) × (4.4.4)
• f(5) = 20(5) × (4.16)
• f(5) = 20(5) × 64
• f(5) = (20.5) × 64
• f(5) = 100 × 64
• f(5) = 6.400

Kesimpulan:

Jadi, hasil dari f(x) = 20(x) × 4³ adalah 6.400
