2). Hasil dari :

= 45 + (-15) × 12 – 72 : (-12)

= 45 + (-15 × 12) – (72 : (-12))

= 45 + (-180) – (-6)

= 45 – 180 + 6

= -129

Jawaban (C). -129

3). Hasil dari :

= 24² – 15² + 18² × 5²

= (24×24) – (15×15) + (18×18) × (5×5)

= (576) – (225) + (324) × (25)

= 576 – 225 + (324 × 25)

= 576 – 225 + (8.100)

= 576 + 7.875

= 8.451

Jawaban (B). 8.451
