12.5.3(b)
Prove that for any positive integer n, 4 evenly divides 32n-1.
Prove the following generalized version of DeMorgan's law for logical expressions:
For any integer n ≥ 2, −(x₁ ^ X₂ ^..^ Xn) = ¬X₁V ¬X₂ V...V ¬Xn.
You can use DeMorgan's law for two variables in your proof: ¬(x₁ ^X₂) = ¬X₁ V ¬X₂.
Define the sequence {bn} as follows:
bo = 1
bn = 2bn-1 + 1 for n ≥ 1
Prove that for n ≥ 0, b₁ = 2n+¹ -1.
