Jawaban:

1) 12.126

2) 279.337

Penjelasan dengan langkah-langkah:

1.) 23³ – 7² + 2³

= (23 × 23 × 23) – (7 × 7) + (2 × 2 × 2)

= (529 × 23) – 49 + (4 × 2)

= 12.167 – 49 + 8

= 12.118 + 8

= 12.126

2) 23⁴ + 2³ – 8³

= (23 × 23 × 23 × 23) + (2 × 2 × 2) – (8 × 8 × 8)

= (529 × 529) + (4 × 2) – (64 × 8)

= 279.841 + 8 – 512

= 279.849 – 512

= 279.337
