Answer:
total number of license plates : 676000
total number of license plates with no repeated letters and no repeated digits : 468000

therefore the total number of combinations for license plates when repetitions of digits and numbers are allowed will be given
26 × 26 × 10 × 10 × 10 = 676000
ii) the number of license plates containing no repeated letters and no repeated digits will be given by
26 × 25 × 10 × 9 × 8 = 468000
