Answer 1

Verified answer

Jawab:
[1.]  = 5.040
[2]  = 6
[3]  = 3.628.800
[4]  = 12
[5]  = 15

Penjelasan dengan langkah-langkah:
[1.]  7! = 7×6×5×4×3×2
= 42×20×6 = 840×6 = 5.040

[2]  ¹²/₅ × ²/₁ + ⁷⁸/₆₅ = ²⁴/₅ + ⁷⁸/₆₅
= ²⁴⁽¹³⁾/₅₍₁₃₎ + ⁷⁸/₆₅ = ³¹²/₆₅ + ⁷⁸/₆₅
= ³⁹⁰/₆₅ = 6

[3]  10! = (10×9×8)×7! = (10×9×8)×5.040
= 90×8 × 5.040 = 720 × 5.040
= 3.628.800

[4]  12/4 = 3, 36/4 = 9
3 + 9 = 12

[5]  5!! = 5 × 3 = 15
