Question

Q.

Diketahui
A = 1²
B = 2²
C = 3²
D = 4²

Maka tentukan

A x B - C + D x D - A ​

Answer 1

Dik:

A = 1²

B = 2²

C = 3²

D = 4²

Maka:

→ A × B - C + D × D - A

= 1² × 2² - 3² + 4² × 4² - 1²

= ( 1 × 1 ) × ( 2 × 2 ) - ( 3 × 3 ) + ( 4 × 4 ) × ( 4 × 4 ) - ( 1 × 1 )

= 1 × 4 - 9 + 16 × 16 - 1

= 4 - 9 + 256 - 1

= ( - 5 ) + 256 - 1

= 251 - 1

= 250

Answer 2

« Penyelesaian Soal »

Diketahui

A = 1²

B = 2²

C = 3²

D = 4²

Maka tentukan

A x B - C + D x D - A

_______________

• A x B - C + D x D - A
• = ( 1² × 2² – 3² + 4² × 4² – 1¹ )
• = ( 1 × 1 ) × ( 2 × 2 ) – ( 3 × 3 ) + ( 4 × 4 ) × ( 4 × 4 ) – ( 1 × 1 )
• = ( 1 × 4 – 9 + 16 × 16 – 1 )
• = ( 1 × 4 ) – 9 + ( 16 × 16 ) – 1
• = ( 4 – 9 + 256 – 1 )
• = ( 4 – 9 ) + 256 – 1
• = ( -5 + 256 ) – 1
• = 251 – 1
• = 250

Kesimpulan

• Hasil =250
