And now we can get our calculator out to evaluate this. So get my TI-85 out, and I get, I'm just going to evaluate this inner expression right over here. So e to the negative 1.73, and from that, I want to subtract one. So that gives me negative 0.822. So that's this part in parentheses. And then I want to multiply it times what I have out front. So my previous answer times, and I won't write the negative just because the negative divided by negative is going to be a positive.
