Penjelasan dengan langkah-langkah:

• 8(2) + 8(2²)
• = ( 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 ) + 8(2²)
• = ( 4 + 2 + 2 + 2 + 2 + 2 + 2 ) + 8(2²)
• = ( 6 + 2 + 2 + 2 + 2 + 2 ) + 8(2²)
• = ( 8 + 2 + 2 + 2 + 2 ) + 8(2²)
• = ( 10 + 2 + 2 + 2 ) + 8(2²)
• = ( 12 + 2 + 2 ) + 8(2²)
• = ( 14 + 2 ) + 8(2²)
• = 16 + 8(2²)
• = 16 + 8(2 + 2)
• = 16 + 8(4)
• = 16 + ( 8 + 8 + 8 + 8 )
• = 16 + ( 16 + 8 + 8 )
• = 16 + ( 24 + 8 )
• = 16 + 32
• = 48

Answer 2

penyelesaian :

= 8(2) + 8(2²)

= 8 × 2 + 8 × 2²

= ( 8 + 8 ) + 8 × ( 2 × 2 )

= 16 + 8 × 4

= 16 + ( 8 + 8 + 8 + 8 )

= 16 + 16 + 16

= 16 × 3

= 48
