Eksponen

Jika a² = a x a , a³ = a x a x a

Maka;

= 20³ : 8 x 3² - 7² + 5²

= (20 x 20 x 20) : 8 x (3 x 3) - (7 x 7) + (5 x 5)

= 8.000 : 8 x 9 - 49 + 25

Dahulukan operasi hitung pembagian lalu perkalian

= (8.000 : 8) x 9 - 49 + 25

= (1.000 x 9) - 49 + 25

= 9.000 - 49 + 25

= 8.976

20³ ÷ 8 × 3² - 7² + 5²

( 20 × 20 × 20 ) ÷ 8 × ( 3 × 3 ) - ( 7 × 7 ) + ( 5 × 5 )

( 400 × 20 ) ÷ 8 × 9 - 49 + 25

8.000 ÷ 8 × 9 - 49 + 25

1000 × 9 - 49 + 25

9000 - 49 + 25

8.951 + 25

8.976
