What is the dissociation of Borax?

I was researching on how to make slime recently for a presentation. The first step was the dissociation of Borax (Na2B4O7*10H2O) into sodium ions and tetraborate ions. I unfortunately do not know how to balance it out because the "*10H2O" confuses me (I haven't quite gone over this with my class). Can someone please write the equation? :(
