Question

1+2^3/2!+3^3/3!+................​

Answer 1

Answer is 6.

Step By Step :-

$= \frac{1 + {2}^{3} }{2} + \frac{ {3}^{3} }{6} \\ \\ = \frac{1 + 8}{2} + \frac{9}{6} \\ \\ = \frac{9}{2} + \frac{3}{2} \\ \\ = \frac{9 + 3}{2} \\ \\ = \frac{12}{2} \\ \\ \\ = 6$

1! = 1

2! = 2

3! = 2×3 = 6

4! = 6 × 4 = 24

5! = 24 × 5 = 120

6! = 120 × 6 = 720

7! = 720 × 7 = 5040
