Ah! The built-in math tags don't recognise \boxed!

Anyways, here is the version in MathJax: (which doesn't load in the comments but it should work for your blog post.)

\(\boxed{C_1\square}_{C_2}(n)=\boxed{C_1}^n_{C_2}(n)\)

\(\square_{C\square}[1]=\square_C\land \square_{C\square}[k+1]=\boxed{\square_{C\square}[k]}_C\)

Also,note that if you copy and paste the LaTeX code in your blog post,it may not work due to tags,so you better type it up manually.
