sqrt 1+sqrt2 + sqrt3+ sqrt4 +sqrt 5= ??    (edited)

 

I'm thinking if it is 225 then the question needs to say that f needs to be an integer too.....well...I guess it DOES!

Back to the drawing board !

I think there is another one....  then f would be 225. I think there is something smaller

I think this works

 

sqrt (1) + sqrt (4) + sqrt (9)+ sqrt (16) + sqrt (25)  =  sqrt (f)

 

1  + 2   +  3   + 4   + 5  =  sqrt (f)

 

15  = sqrt (f)      square both sides

 

225  = f

 

 

cool cool cool
