Answer 1

b)4!−2!=4×3×2×1−2×1=24−2=22

c)7! - 4! = 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 - \times 4 \times 3 \times 2 \times 1 = 5.040 - 24 = 5.016c)7!−4!=7×6×5×4×3×2×1−×4×3×2×1=5.040−24=5.016

d)6! - 5! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 - 5 \times 4 \times 3 \times 2 \times 1 = 720 - 120 = 600d)6!−5!=6×5×4×3×2×1−5×4×3×2×1=720−120=600

e)5! - 2! = 5 \times 4 \times 3 \times 2 \times 1 - 2 \times 1 = 120 - 2 = 118e)5!−2!=5×4×3×2×1−2×1=120−2=118

f)4! - 3! = 4 \times 3 \times 2 \times 1 - 3 \times 2 \times 1 = 24 - 6 = 18f)4!−3!=4×3×2×1−3×2×1=24−6=18

g)7! - 5! = 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 - 5 \times 4 \times 3 \times 2 \times 1 = 5.040 - 120 = 4.920g)7!−5!=7×6×5×4×3×2×1−5×4×3×2×1=5.040−120=4.920
