World's Hardest Math Problem

I always thought it might be interesting to check out a few of the world hardest math problems. Unfortunately finding and or explaining the answers to these problems would be a copy paste from some genius website and would most likely tale about 10 pages long. So, I'll post some of the hardest and if anyone can solve one I will give you my life savings (10 cents). Alright here we go! 

Question 1

Give the value, to three significant figures, of x.

[15 marks]

Question 2

An isosceles triangle is drawn so that it has the same area as the above square (i.e. x), and with two sides that are equal to the square root of x (henceforth dubbed y). What is the length of the third side?

[100+90-7685*58/92 marks]

Question 3

Prove that the triangle above exists.

[25 marks]

Question 4

What is the area of a octagon of side length y, in cubic inches. (Note that this question uses non-euclidean goemetry)

[2πr marks]

Question 5

Through cunning use of Pythaogoras' Theorem, prove that aliens do not exist.

[-0 marks]

Question 6

If Failed to parse (lexing error): 48y^2+πy-6778=x , then what does y smell like?

Yes you are right. #6 does ask what y smells like. I don't know if that is a real thing but I assume it is. Yes math is wierd.
