WebEuclid's lemma. In algebra and number theory, Euclid's lemma is a lemma that captures a fundamental property of prime numbers, namely: [note 1] Euclid's lemma — If a prime p divides the product ab of two integers a and b, then p must divide at least one of those integers a or b . For example, if p = 19, a = 133, b = 143, then ab = 133 × 143 ... WebSo, by the principle of mathematical induction P(n) is true for all natural numbers n. Problem 2 : Use induction to prove that 10 n + 3 × 4 n+2 + 5, is divisible by 9, for all natural numbers n. Solution : Step 1 : n = 1 we have. P(1) ; 10 + 3 ⋅ 64 + 5 = 207 = 9 ⋅ 23. Which is divisible by 9 . P(1) is true . Step 2 : For n =k assume that P ...
