Practice problem
Let set A be all numbers of the form 4x4^x4x, where x∈Nx \in \mathbb{N}x∈N. Which of the following sets B is NOT disjoint with AAA?
16x∣x∈N+16^x | x \in \mathbb{N}^{+}16x∣x∈N+
2x+1∣x∈N+2x + 1 | x \in \mathbb{N}^{+}2x+1∣x∈N+
3x∣x∈N+3^x | x \in \mathbb{N}^{+}3x∣x∈N+
Type a concept, like “slope” or “photosynthesis”.
