The binomial coefficients are defined in Exercise of Section. Use induction on to prove that if is a prime integer, then is a factor of for . (From Exercise of Section, it is known that is an integer.) b. Use induction on to prove that if is a prime integer, then is a factor of . WebbProve by mathematical induction that 2^n < n! for all n ≥ 4. Expert Answer 100% (1 rating) 1st step All steps Final answer Step 1/2 Explanation: To prove the inequality 2^n < n! for all n ≥ 4, we will use mathematical induction. Base case: When n = 4, we have 2^4 = 16 and 4! = 24. Therefore, 2^4 < 4! is true, which establishes the base case. tes psikotes gambar orang pdf
