Answer 1

Jawaban:

Penyelesaian :

No 1 :

• 50² + 10²

• = ( 50 × 50 ) + ( 10 × 10 )

• = 2.500 + 100

• = 2.600

No 2 :

• 80² - 70² × 2

• = ( 80 × 80 ) - ( 70 × 70 ) × 2

• = 6.400 - 4.900 × 2

• = 6.400 - ( 4.900 × 2 )

• = 6.400 - 9.800

• = -3.400

No 3 :

• 100²

• = 100 × 100

• = 10.000

Answer 2

Penjelasan dengan langkah-langkah:

50² + 10²

= (50 × 50) + (10 × 10)

= 2.500 + 100

= 2.600

80² - 70² × 2

= (80 × 80) - (70 × 70) × 2

= 6.400 - 4.900 × 2

= 6.400 - 9.800

= -3.400

100²

= 100(100)

= 10.000
