HELPPPP!!!! sepcific
explanation is best !!! this is discrete mathematics content.
1. Prove, or disprove by finding a counterexample: If a|bc where a,b and c are positive integers then a b or a c. 2. Let n be an odd integer. Show that there is an integer k such that n2 = 8k +1.
This is discrete mathematics.
Please solve it step by step. Thank you so much.
