Can a transcendental number such as pi, be raised to an irrational, but algebraic power resulting in an algebraic solution? Complex solutions would be acceptable. There might be a quick proof here, or there might not be. - Thanks for any help you can offer answering this! (And I promise that this isn't for a class or anything like that!)

Mathfilter: In Gelfand's exceptional Algebra
text, he is talking about the formula 1 + x + x^2 + x^3 + ... = 1/(1 - x). He uses the Achilles racing the tortoise model when first introducing the formula. He discusses the case x = 10, whence 1 + 10 + 100 + 1000 + ... = -1/9. [more inside]

Warning: wait to read this question until tomorrow if you are in Learned League.
So, today one of the Learned League questions was, What is the y-intercept of the line with the following equation?: 3y-11x = 39. I couldn't get any further than y = 13 + 3 2/3 x or y = 13 +3.66666x. Actually it appears the response is 13. How does one get to the right response for this question?

But Sir, what is x? Teaching students algebra for the first time. They keep wanting to put values in for x, and write that down.
E.g. x + x = . Becomes 1 + 1 = 2, in their books. Whereas I want x + x = 2x.
Does anyone have any strategies, or techniques to overcome this? [more inside]

Is there an easy-to-use computer program (other than TI Interactive) I can use to draw graphs of functions when I'm writing my Algebra 2 tests? [more inside]
