Penjelasan dengan langkah-langkah:

9³ + 7³ + 2³

(9.9.9) + (7.7.7) + (2.2.2)

729 + 343 + 8

1.072 + 8

= 1.080

3² × 4² + 2²

(3.3) × (4.4) + (2.2)

9 × 16 + 4

144 + 4

= 148

1.

= 9³ + 7³ + 2³

= (9×9×9) + (7×7×7) + (2×2×2)

= 729 + 343 + 8

= 1.072 + 8

= 1.080

2.

= 3² × 4² + 2²

= (3×3) × (4×4) + (2×2)

= 9 × 16 + 4

= 144 + 4

= 148
