Answer 1

21

a = 2³ × 3² × 5

a = 8 × 9 × 5

a = 40 × 9

a = 360

_____________

b = 2 × 3³ × 7

b = 2 × 27 × 7

b = 2 × 189

b = 378

___________

c = 3 × 5 × 7²

c = 15 × 49

c = 735 → numarul natural

___________________

d = 2² × 3 × 5²

d = 4 × 3 × 25

d = 3 × 100

d = 300 → numarul natural

______________________

e = 7 × 11 × 13

e = 77 × 13

e = 1 001 → numarul

_________________

f = 2² × 11 × 17

f = 4 × 11 × 17
