## Let's play: math problems with a comm major!

I'm having trouble wrapping my head around a math equation I need to create, possibly because the data I have to cook something up with is less than ideal and only good for faking a preliminary number. Maybe you can help...

## Can a transcendental number raised to an algebraic power be algebraic?

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!)

## 1 + 10 + 100 + ... = -1/9

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.

## Can't Figure Out Why I Can't Figure It Out

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?

## Answering to Sir What is x

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?
