Answer 1

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

Step-by-step 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.
