#3**+5 **

x=x^(1/2^y)=5, where y=the number of nested squares.E.g., if you have 5 nested squares, then y would be 2^5=32. So x^1/32=5.

#4**+20 **

Best Answer

\(\sqrt{X+\sqrt{X+\sqrt{X+...}}}=5\\ Let\\ Y= \sqrt{X+\sqrt{X+\sqrt{X+...}}}\qquad where\;\;\;Y=5\\ Now\\ \sqrt{X+Y}=5\\ X+Y=25\\ but\; Y=5\\ X+5=25\\ X=20\)

Thanks YangShizzle,Melody and Guest for anweser my question!

Melody ,that is a very cool way to do it!

i think this way is easear

sqrt{X+\sqrt{X+\sqrt{X+...}}}=5

sqrt{5x4+\sqrt{5x4+\sqrt{5x4+...}}}=5 if it is + you will bring 5 if it is - you will bring 4

let s say:

sqrt{12+\sqrt{12+\sqrt{12+...}}}=x

we can write it like

sqrt{4x3+\sqrt{4x3+\sqrt{4x3+...}}}=x so x will be 4 because + we choosing bigger one
