WebFind the smallest positive integer for which P (n): 2 n < n! is true, put n = 2, 3, 4, 5 in P (n). n! = n × ( n − 1) × ( n − 2).... × 3 × 2 × 1 Put n = 2 L.H.S = 2 n = 2 2 = 4 R.H.S = n! = 2! = 2 Here, 4 < 2, which is not possible Hence, n = 2 is not the smallest positive integer for which P (n): 2 n < n! is true. Put n = 3 L.H.S = 2 n = 2 3 = 8 Web13 mei 2015 · Raghunath Reddy Given n is a natural number, then 92n – 42n If n = 1 then 81 - 16 = 65 is always divisible by both 5 and 13. if n = 2 then 6561 - 256 = 6305 is always divisible by both 5 and 13. ∴ Option C is correct.

Applying the same, 2 np3 = 100 np2 => np3 = 50 np2 n! / (n-3)! = 50 * (n! / (n-2)! ) So, 50 = (n! * (n-2)!)/ (n! * (n-3)!) or 50 = (n-2) (n-3)! / (n-3)! => 50 = n-2 n = 52 A) 212 B) 44 Web30 jan. 2024 · 1.
