Explanation
- The word ARGENTINA has 9 letters, and some of these letters are repeated (2Ns, 2Ts, and 2As). To calculate the number of unique words that can be formed using these letters, we need to divide the total number of permutations (9!) by the number of repetitions: 9! / (2! × 2! × 2!)
- This formula accounts for the repetitions of the N, T, and A letters, and gives us the total number of unique words that can be formed using the letters of the word ARGENTINA.
