Summing data columns in a series

If I have a 2 data columns and I want to raise them to the power of K and sum the using sigma notation from k=1 to 10 how would I do that. So far I have tried.

Datacolumn1; %defined variables
Datacolumn2;
f=0;
for k=1:10
    Data=(Datacolumn1.^k-Datacolumn2.^k).^2; %I want datacolumn1.^k minus datacolumn2.^k all squared summed(sigma notation) from k=1:10
    f=f+Data
end

Have I entered that correctly. Any help would be appreciated.

I want to raise them to the power of K and sum the using sigma notation from k=1 to 10

k=?? % define 
Data=Datacolumn1.^k+Datacolumn2.^k;
result=sum(Data(1:10));

If your code is correct? then

k=?? % define 
Data=(Datacolumn1.^k-Datacolumn2.^k).^2; 
result=sum(Data(1:10));

Hi thanks the question is written as Sigma(K=1 on the bottom to 10 on top) (Datacolumn1^k-Datacolumn2^k) ^2

[KALYAN ACHARJYA]

Is this?

k=?? % define 
Data=(Datacolumn1.^k-Datacolumn2.^k).^2; 
result=sum(Data(end-9:end));

Hi there would I not need a for loop as k starts at 1 and goes to 10 for sigma. I think its just the root mean square error with k powering the vectors.
