Diketahui :
• z → 5
• x → 10
• y → 15
Ditanya :
• 2z × x² + y(y) = ?
Jawab :
• 2z × x² + y(y)
• = 2(5) × 10² + 15(15)
• = ( 2 + 2 + 2 + 2 + 2 ) × 10² + 15(15)
• = ( 4 + 2 + 2 + 2 ) × 10² + 15(15)
• = ( 4 + 4 + 2 ) × 10² + 15(15)
• = ( 8 + 2 ) × 10² + 15(15)
• = 10 × 10² + 15(15)
• = 10 × ( 10 × 10 ) + 15(15)
• = 10 × 100 + 15(15)
• = 10 × 100 + ( 15 × 15 )
• = 10 × 100 + 225
• = ( 10 × 100 ) + 225
• = 1.000 + 225
• = 1.225

Penyelesaian :
Diketahui :
• z → 5
• x → 10
• y → 15
Ditanya :
• 2z × x² + y(y) = ?
Jawab :
• 2z × x² + y(y)
• = 2(5) × 10² + 15(15)
• = ( 2 + 2 + 2 + 2 + 2 ) × 10² + 15(15)
• = ( 4 + 2 + 2 + 2 ) × 10² + 15(15)
• = ( 4 + 4 + 2 ) × 10² + 15(15)
• = ( 8 + 2 ) × 10² + 15(15)
• = 10 × 10² + 15(15)
• = 10 × ( 10 × 10 ) + 15(15)
• = 10 × 100 + 15(15)
• = 10 × 100 + ( 15 × 15 )
• = 10 × 100 + 225
• = ( 10 × 100 ) + 225
• = 1.000 + 225
• = 1.225
→ Kesimpulan : ↓
Hasil nya adalah 1.225
