1. 13
2. both 5 and 13
3. 5
4. none of the above
Correct option is (2) both 5 and 1392n - 42n is of form an - bn (where n is even)Therefore an - bn is always divisible by (a - b) & (a + b)So, it is divisible by (9 + 4) and (9 - 4) i.e., 5 and 13
Correct option is (2) both 5 and 13
92n – 42n is of form an – bn (where n is even)
Therefore an – bn is always divisible by (a – b) & (a + b)
