- Rule 2: If w is any word in L1, then xw is also in L1.

Answer :

Final answer:

L1 is a language that contains words starting with the letter x, followed by any combination of letters.

Explanation:

The language represented by L1 follows two rules:

  1. Rule 1 states that the letter x is in L1.
  2. Rule 2 states that if w is any word in L1, then xw is also in L1.

Based on these rules, we can deduce that L1 contains words that start with x and can be followed by any combination of letters.
