【解析】Proof: (By the Principle of Mathematical Induction)Pn is that “3n =1 + 2n (mod 4)(1)If n=1, 3'≡1+2(mod4) is true..P1 is true.(2)If Pk is true, then3^k=1+2k(mod4)∴3^(k+1)=3*3^k 3(1+2k)(mod4)≡3+6k(mod4)≡3+2k(mod4)=1+2[k+1](mod4). P1...
Prove the following using a combinatorial proof. Let n and k be integers with 1 "less than or equal to" k "less than or equal to" n . Show that: ? n k + 1 ( n k ) ( n k ? 1 ) = 1 2 ( 2 n + 1 n + 1 )
