Answer:

12,338,352 companies

Explanation:

If the companies' names can have either 4 or 5 letters, and teh letters can repeat themselves, then the total number of companies that can be listed on NASDAQ is:

4 letter names = 26 x 26 x 26 x 26 = 26⁴ = 456,976

5 letter names = 26 x 26 x 26 x 26 x 26 = 26⁵ = 11,881,376‬

total number of companies listed = 456,976 + 11,881,376‬ = 12,338,352
