=(8×6)×(4×2)+(6×4×2)
=(48×8)+(24×2)
=384+48
≈432
2.) 8⁹+65²
≈(8×8)×(8×8)×(8×8)×(8×8)×8)+(65×65)
≈(64×64)×(64×64)×8)+(4.225)
≈(4.096×4.096×8)+4.225
≈(16.777.216×8)+4.225

3.) 90²+40²
≈(90×90)+(40×40)

Penjelasan dengan langkah-langkah:
8!! + 6!!
= (8 × 6 × 4 × 2) + (6 × 4 × 2)
= (48 × 4 × 2) + (24 × 2)
= (192 × 2) + 48
= 384 + 48
= 432
8⁹ + 65²
= (8 × 8 × 8 × 8 × 8 × 8 × 8 × 8 × 8) + (65 × 65)
= (64 × 64 × 64 × 64 × 8) + 4.225
= (4.096 × 64 × 64 × 8) + 4.225
= (262.144 × 64 × 8) + 4.225
= (16.777.216 × 8) + 4.225
= 134.217.728 + 4.225
= 134.221.953
90² + 40²
= (90 × 90) + (40 × 40)
= 8.100 + 1.600
= 9.700
