how can i simplify ((1)/(∑x^2))=((1)/(∑x))

To simplify the equation 

\[
\frac{1}{\sum x^2} = \frac{1}{\sum x}
\]

we can start by cross-multiplying to eliminate the fractions:

\[
\sum x \cdot 1 = \sum x^2 \cdot 1
\]

This simplifies to:

\[
\sum x = \sum x^2
\]

Thus, the simplified form of the original equation is:

\[
\sum x = \sum x^2
\]

This result indicates that the sum of the \(x\) values must equal the sum of the squares of those \(x\) values for the original equation to hold true.
