Answer 1

f(x) = x! + x(x) × 13

f(5) = ...

cara Penyelesaian :

f(x) = x! + x(x) × 13

f(5) = 5! + 5(5) × 13

f(5) = ( 5.4.3.2.1 ) + ( 5 × 5 ) × 13

f(5) = 120 + ( 25 × 13 )

f(5) = 120 + 325

f(5) = 445

Answer 2

Jawaban:

f(x) = x! + x(x) × 13

• 5! + 5(5) × 13
• (5 × 4 × 3 × 2 × 1) + (5 × 5) × 13
• (20 × 3 × 2 × 1) + (5 × 5) × 13
• (60 × 2 × 1) + (5 × 5) × 13
• (120 × 1) + (5 × 5) × 13
• 120 + (5 × 5) × 13
• 120 + 25 × 13
• 120 + (25 × 13)
• 120 + 325
• 445
