9!! + 7!! - 2²
= (9×(9-2)×(9-4)×(9-6)×(9-8) + (7×(7-2)×(7-4)×(7-6) - 2^2
= (9×7×5×3×1) + (7×5×3×1) - (2.2)
= (63×15) + (35×3) - 4
= 945 + 105 - 4
= 1.050 - 4
= 1.046

Jawaban:
9!! + 7!! - 2² = 1.046
Penjelasan dengan langkah-langkah:
9!! = 945
→ 9 × 7 × 5 × 3 × 1 = 945
CARANYA ↓
→ 9 × 7 = 63
→ 63 × 5 = 315
→ 315 × 3 = 945
→ 945 × 1 = 945
7!! = 105
→ 7 × 5 × 3 × 1 = 105
CARANYA ↓
→ 7 × 5 = 35
→ 35 × 3 = 105
→ 105 × 1 = 105
2² = 4
CARANYA ↓
→ 2 × 2 = 4
HASILNYA ↓
→ 945 + 105 - 4 = 1.046
