how i convert r=1.859494566887529 to (18627-sqr​t(50225239​))/6206

r=1.859494566887529

[OCDER]

Is there a question for us?

[Adam Danz]

(18627 - sqrt(50225239)) / 6206  
ans =
     1.8595

What are you converting?

[sadeem alqarni]

i want the (command) which makes this number (r=1.85949456688752) as a figure root

[OCDER]

Still not clear. What do you mean by "figure root"? What is so special about this number?

[Adam Danz]

Sadeem, the reason we're confused is that there are an infinite number of equations that equal 1.8595...

For example, the fraction below. It sounds like you want one involving a square root but where does 18627 and 6206 come from?

2 + 1/(-7 + 1/(-9 + 1/(2 + 1/(7))))

[sadeem alqarni]

in mathmatica programs i use this: RootApproximant[ 1.859494566887529',2] this is equal= (18627-sqrt(50225239))/6206

[Adam Danz]

I see. I'm not familiar with a matlab equivalent but there could be. Here's documentation on RootApproximant.

Sadeem, how is your question here any different from the one you asked back in March (link above)?
