I would take my G minus 27, I would increment this exponent by one, so let's see negative 2 3rds plus one is positive 1 3rd, so positive 1 3rd power, and then I would divide by this new exponent, so dividing by 1 3rd is the same thing as multiplying by three, so that's the left hand side. This is going to be equal to, the right hand side, this is just going to be negative T, and for good measure, I'm going to have a plus C right over here. So how can we solve for C? Well they give us some information. They say G of zero is equal to 91, so let's write that down. So when T is zero, G is 91, so we can write, let me write it over here. So three times, so when T is zero, G is 91.
