Question

Hitunglah hasil dari: a. 5! - 4! b. 4! x 5! pake cara yah

Answer 1

>>>>soal a<<<

5! - 4! = 5×4×3×2×1 - 4×3×2×1
          = 120 - 24
          = 96

>>>>soal b <<<<

4! x 5! = (4×3×2×1) (5×4×3×2×1)
           = (24) (120)
           = 2880

jadi kalau faktorial itu tinggal dijabarin saja kebelakang
misalkan 3! = 3×2×1

Answer 2

A. 
5! - 4! = 5x4x3x2x1 - 4x3x2x1 = 120 - 48 = 72

B.
4! x 5! = 4x3x2x1 x 5x4x3x2x1 = 48 x 120 = 5760
