How to write a really long equation?

Hello everyone. I am a kind of new learner of MATLAB. I need to write the attached equation but I always get errors. Are there anyone who can write the correct version of it?

Btw x an y will be arrays.

Thank you everybody.

term1 = (log(x.^(-2) .* y.^3) .* 10^3 .* y.^abs(x)) ./ ...
        (factorial(4) .* 2.8 ./ 3.16 );

term2 = (2.^(1/3) .* 5 + 6 .* 2.^(-2) ./ 3.^2 .* 4 .* ln(8./sqrt(x.*y)) ) ./ ...
        (exp(0.2 .* x) .* sin(y.^(-2)).^2 .* abs(cos(x-u)).^(1/3) .* 0.25);

z = term1 + term2;

I have written this in vectorized form, so x and y can be vectors (or arrays) and you would get out a vector (or array) result.
