AI Thread Summary
The discussion revolves around whether the summation of a number can equal its square root, with participants exploring various mathematical interpretations. One participant suggests the equation x + x = √x, prompting further clarification on what is meant by "summation of a number." The conversation touches on the sum of integers and potential connections to the Riemann zeta function when considering infinite sums. There is confusion over terminology, particularly regarding the concept of summation and its mathematical implications. Ultimately, the participants agree that while simple cases like √1 = 1 exist, more complex or non-trivial relationships remain uncertain.

Can the summation...

Can the summation of a number equal that numbers square root??
 
Physics news on Phys.org
How can you sum a single number?
 
Well, I think that
\sqrt{1}=1
and
\sqrt{0}=0
both work...
 
whatzzupboy:
Did you mean something like this:
Has the following equation any solutions:
x+x=\sqrt{x} ?
 
There's something weird-------->fishy here,so let's see whether he can ask a logically valid question...:wink:

Daniel.
 
for example:
<sum> of x^y
can it equal the square root of y

What's the variable you sum after and what possible values can it take...?

Daniel.
 
any I am just asking though is there any way at all that the summation of a number equal its square root
 
It still doesn't make any sense,sorry...Are u referring to a power/geometric series...?

Daniel.

no I'm saying if u take the summation of any number can its factors equal the numbers square root

Summation notain of x^1 to (x-1)^1= 1^1+2^1+3^1+4^1...(x-1)^1

You mean something like:
\sum_{k=1}^{n} k^{power}

If the sum streches to infinity,then there could be made a connection to the zeta-Riemann function...

This is grade K-12 Dex...

Whatzzupdude, please try to explain what you exactly mean by 'summation of a number'.

What ARE you talking about??
This is the sum of of the first (x-1) integers; it is not a summation "notain" (whatever that is) of x^1 to (x-1)^1.

Thank you Dextercioby, that is exactly what I meant can
\sum_{k=1}^{n} k^{power}
equal the root of n

i think that he means

x^y=x + y?

if so than 2^2= 2+2...but I seirously doubt that's what you mean

why don't you add the definition summation into the glossary :)
 
  • #16
You're asking if

\sum_{k=1}^n k^a = \sqrt{n}

for some constants a and n?

--J
 
  • #17
yes that is exactly what i mean
 
  • #18
\sum_{k=1}^1 1^1 = \sqrt{1}

Not sure about non-trivial ones though.
