Answer 1

We can add factorial of 3 five times
3!+3!+3!+3!+3!=30

Answer 2

1 + 3! + 5+ 7 + 11 = thirty

Step-by-step explanation:

3! + 3! + 3! + 3! + 3!      = 30 

3! + 1 + 3 + 9 + 11          = 30

1 + 5 + 7 + 3! + 11               = 30

3! + 3! + 3! + 11 + 1             = 30

3! + 3! + 11 + 5 + 1               = 30

11+ 1 + 1 + 3! + 11              = 30

15 + 3 + 3 + 3 + 3!              = 30

13 + 1 + 1 + 9 + 3!            = 30

133! + 3! + 3! + 3! + 3!      = 30 

3! + 1 + 3 + 9 + 11          = 30

 1 + 5 + 7 + 3! + 11               = 30

3! + 3! + 3! + 11 + 1             = 30

3! + 3! + 11 + 5 + 1               = 30

11+ 1 + 1 + 3! + 11              = 30

15 + 3 + 3 + 3 + 3!              = 30

13 + 1 + 1 + 9 + 3!            = 30

 13 + 1 + 3 + 7 + 3!            = 30

 13 + 5 + 3 + 3 + 3!            = 30

11 + 3 + 7 + 3!            = 30

13 + 5 + 3 + 3 + 3!            = 30
