5(3)² × 4! – 6² × 12!! = ..​

Penjelasan dengan langkah-langkah:

5(3)² × 4! – 6² × 12!! =

= 5(9) × (4 × 3 × 2 × 1) – (6 × 6) × 12!!

= (45 × 24) – 36 × (12 × 10 × 8 × 6 × 4 × 2)

= 1.080 – (36 × 46.080)

= 1.080 – 1.658.880

= -1.657.800

–1.648.040

Penjelasan dengan langkah-langkah:

= 5(3)^2 × 4! – 6^2 × 12!!

= 5(3 × 3) × (4 × 3 × 2) – 36 × 12!!

= 5(9) × 24 – 36 × (12.10.8.6.4.2)

= 10840 – 36(46080)

= 10840 – 1.658.880

= -1.648.040
