Question

Helpppppppp !!!
5! × 5^2

A . 1275
B . 1500
C. 1350
D. 2000​

Answer 1

3000

Explanation:

A factorial is the product of all the positive integers from 1 to n —symbol n!

Another definition is the product of an integer and all the integers below it; (e.g. factorial four (4!) is equal to 24).

5! = 5 factorial = 5x4x3x2x1

Times 5 by 4

5! = 20x3x2x1

Times 20 by 3

5! = 60x2x1

Times 60 by 2

5! = 120

5^2 is '5 squared' or
`5^(2)`, which is 5x5.

5x5 = 25

120 x 25 = 3000 which is not on the list so I don't know, I've done it on my calculator and it comes up with 3000.

Answer 2

`\boxed{\sf n!=n(n-1)(n-2)\dots}`

`\\ \sf\longmapsto 5!(5^2)`

`\\ \sf\longmapsto 5(4)(3)(2)(1)(25)`

`\\ \sf\longmapsto 120(25)`

`\\ \sf\longmapsto 3000`
