Answer 1

There can be many answers but the basic idea is using factorial. Factorial is the product of all the numbers from 1 to that number. For example 4! = 1 x 2 x 3 x 4 = 24.
 
So, 3! + 11 + 13 = 30
Similarly you can find many such answers.

Hope that helps !!

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
