Let's solve the equation x^x^x^x^... = 2, where x^x^x^x^... has infinite exponents. To solve it, the x^x^x^x^... in the exponent has to equal 2 as well, so we get x^2 = 2, or x = √2.

Using the same technique for the equation x^x^x^x^... = 4, we get x^4 = 4, and x = 4^(1/4) = √2. However, we also showed that x^x^x^x... = 2, therefore 2 = 4, right??

He said that in the future, we will have no use for the steering wheel. All vehicles will be compact. They will constantly be communicating to the GPS system the vehicles speed, location, and direction. We simply select our destination on a map. The vehicle will use GPS to take us the most convenient route. We won't have windows because our vehicles will do some crazy stuff, driving on the left side of the street, running stop lights, and zooming between 2 other vehicles at 70 mph, because hey... all vehicles will be in constant sync with each other to avoid collision. Just in case the system does fail, your vehicle will stop in the middle of the road. All surrounding vehicles will be alerted to maneuver our your vehicle (similar to how a car breaks down on the side of the road). Older human-steered vehicle will have GPS attached to their car so that all the GPS system can locate them. They will be the only ones required to follow traffic laws.

I need to know if the transcendental numbers closed under the operations of addition, subtraction, multiplication, and division. I also need to know why or why not. I also need to know if the imaginary numbers are closed under those operations. I also need to know where I can find the information on the internet.

Thank you.
