So these guys cancel, this guy becomes negative. And now we have the denominator on this term here. This equation is called a nurse equation and it can be used, used to find a cell voltage under non standard state conditions whereas this guy is our cell voltage under nonsense state conditions. So we basically plug this guy in and all these guys in and we get our cell voltage for nonstand state conditions. Now, this guy can be simplified even further because notice we have a constant R, a constant F. And if we're given some constant temperature, say 25 degrees Celsius, the most common temperature, room temperature, we can plug these guys in and simplify this whole guy to simply this guy here. Look, we rewrite this formula, we get this.
