So, my professor me gave this exercise as a challenge:
-First, prove that:
1+11+11+11+11+...=1+√52.
-Then, prove that:
1+11+11+11+11+...=√1+√1+√1+√1+...
He said you need no advanced maths to solve it: you just need high-school math with no calculus...
The thing is that it's been 2 weeks now and I'm as lost as when I first saw the problem.
Can someone help me!
