# In 4—6, describe L 1 L 2 ,   L 1 ∪ L 2 , and ( L 1 ∪ L 2 ) * for the given languages L 1 and L 2 .6. L 1 iis the set of all strings of 0’s and l’s that start with a 0 ;   L 2 is the set of all strings of 0’s and l’s that end with a 0.

To determine

Find

Describe L1,L2,L1L2 and (L1L2)* for the given

L1 is the set of all strings of 0's and 1's that start with a 0, and L2 is the set of all strings of 0's and 1's that end with a0.

Explanation

Given information:

Describe L1,L2,L1L2 and (L1L2)* for the given

Languages L1 and L2.

Concept used:

:Union {}*:Kleen closure

Calculation:

It is given that L1 is a set of all strings of 0's and 1's that start with a 0 and L2 is a set of all strings of 0's and 1's that end with a 0. Since L1L2 is a string made from concatenation of elements of L1 and L2 so L1L2 can be defined in words as
