- Simplify the following expression: ((x∈A)∧(x∈B)∧(x∉C))∨((x∈A)∨(x∈B))((x \in A) \land (x \in B) \land (x \notin C)) \lor ((x \in A) \lor (x \in B))((x∈A)∧(x∈B)∧(x∈/C))∨((x∈A)∨(x∈B))
- Let xxx be a positive integer and consider the two sets A={x2,2x}A = \{x^2, 2x\}A={x2,2x} and B={x,10x−24}B = \{x, 10x-24\}B={x,10x−24}. Find the lowest possible value of xxx su…
