And it's easily proven:
If 2^x - 1 is prime, then neither 2^x - 1 nor 2^x is divisible by 3. Of any 3 consecutive integers, one must be divisible by 3. Therefore 2^x + 1 is divisible by 3.
Therefore 2*(2^x+1) = 2^(x+1) + 2 is divisible by 3, and so is 2^(x+1) - 1.
A (completely useless) counterexample: Let x = 2.
... but seriously, how is access to a broadband Internet connection a legal right? Somebody please explain this to me, because the article doesn't give any supporting logic.
They made a law that says everyone gets it. Isn't that all something needs to be a legal right?
Fire the vehicle examiner. You only need 1 crumple zone in an impact; it doesn't matter what car it's on. The Hummer will use the Volvo's body as the crumple zone, simple as that. This is high school physics.
Have you ever actually *seen* collisions of large SUVs and trucks with light cars? The SUVs AND their passengers fare significantly better than the other car and its passengers, by far most of the time. You have a stiff bumper hitting a much softer part of a car body, which absorbs all of the impact.
Way to fight the stereotype of SUV owners being selfish dicks!
