1.) 54² – (10²)²

1.) 54² – (10²)²

= 2.916 – 10^2×2

= 2.916 – 10⁴

= 2.916-10.000

= -7.084

2.) ⅝ + ⅔ – ½

= 15/24 + 16/24 – 12/24

= 19/24

~~~ CAMPURAN ~~~

1) 54² – ( 10²)²

→ 54² – 10 ( 2 × 2 )

→ 54² – 10⁴

→ [ 54.54 ] – [ 10.10.10.10 ]

→ 2.916 – 10.000

→ [ –7.804 ]

2) 5/8 + 2/3 – 1/2

→ 15/24 + 16/24 – 12/24

→ 31/24 – 12/24

→ 19/24
