Q.


20² + 29³ - 12³

10² × 6!! - 2⁴ ​

Answer 1

Penyelesaian :

No 1 :

• 20² + 29³ - 12³

• = ( 20 × 20 ) + 29³ - 12³

• = 400 + 29³ - 12³

• = 400 + ( 29 × 29 × 29 ) - 12³

• = 400 + ( 841 × 29 ) - 12³

• = 400 + 24.389 - 12³

• = 400 + 24.389 - ( 12 × 12 × 12 )

• = 400 + 24.389 - ( 144 × 12 )

• = 400 + 24.389 - 1.728

• = ( 400 + 24.389 ) - 1.728

• = 24.789 - 1.728

• = 23.061

No 2 :

• 10² × 6!! - 2⁴

• = ( 10 × 10 ) × 6!! - 2⁴

• = 100 × 6!! - 2⁴

• = 100 × ( 6 × 4 × 2 ) - 2⁴

• = 100 × ( 24 × 2 ) - 2⁴

• = 100 × 48 - 2⁴

• = 100 × 48 - ( 2 × 2 × 2 × 2 )

• = 100 × 48 - ( 4 × 2 × 2 )

• = 100 × 48 - ( 4 × 4 )

• = 100 × 48 - 16

• = ( 100 × 48 ) - 16

• = 4.800 - 16

• = 4.784
