MATLAB: Calculate Exponentials WITHOUT built-in exponent function

exponentialsfor loopsMATLABtaylor series

Greetings!
I am new to MATLAB and going in circles trying to logic my way what should be a simple function:
How do I calculate, using a "for" loop, x^k?
My function inputs are ( x, n ); I start with:
% code
ExpValue = 0;
k = 1;
for i = 1:n;
  ExpValue = ExpValue + ?
end
Recall that I must use a Sum for the exponential function… x*1, x*x, x*x*x all the way to squaring x up to n times.
Thanks!

Trying to compute x^n using only summation is a terrible method. Surely you would be allowed to use multiplication!
   ExpValue = 1;
   for k = 1:n   % (Corrected)
     ExpValue = ExpValue*x;
   end
