If you want help, then start by showing what you tried. It is easier to correct what you write than it is to write code from scratch, and you will learn more.
And if one expression is too large, then start by learning how to break it into pieces. For example, can you write the natural log function? In MATLAB, that is just log, NOT ln. And log with the base 2 is just log2.
Break a large problem into small ones. Figure out how to write each little piece.

Break it down into constituent terms to make it easier to write. See if this is what you're after.
% some fake data
x = 1:10;
y = x+1;
% the terms
t1 = 1./sqrt(1 + (1 + y.^3).^(2/3)) + 0.3;
t21 = (exp(y/5).*3.^((x-1)./y)); % the denominator is 1
t22 = cos((x.*y).^(1/3)).^2;
t23 = log2((x.^2)/4);
t3 = log(x + y);
% put it all together
z = t1 + t21.*t22.*t23 + t3;
