Question

А) 4!; б) 5!; в)4!+5!; г)4!×5!д)5×4!

Answer 1

А)4!=1×2×3×4=24
б)5!=1×2×3×4×5=120
в)4!×5!=24(1×2×3×4)×120(1×2×3×4×5)=2880
г)5×4!=5×24(1×2×3×4)=120

Answer 2

Let's calculate the values:

а) 4! means factorial of 4. 4! = 4 × 3 × 2 × 1 = 24.

б) 5! means factorial of 5. 5! = 5 × 4 × 3 × 2 × 1 = 120.

в) 4! + 5! means the sum of the factorials of 4 and 5. 4! + 5! = 24 + 120 = 144.

г) 4! × 5! means the product of the factorials of 4 and 5. 4! × 5! = 24 × 120 = 2,880.

д) 5 × 4! means 5 multiplied by the factorial of 4. 4! = 24. 5 × 4! = 5 × 24 = 120.

So, the values are: а) 4! Answer: 24

б) 5! Answer: 120

в) 4! + 5! Answer: 144

г) 4! × 5! Answer: 2,880

д) 5 × 4! Answer: 120
