Suppose a company needs temporary passwords for the trial of a new time management software. Each password will have two letters followed by two digits. The digits 7, 8,9 will not be used. So, there are 26 letters and 7 digits that will be used. Assume that the letters and digits can be repeated. How many passwords can be created using this format?
