1. The input "Nm\n2\n2\n /C\n2\n2" appears to be a sequence of characters and numbers without a clear mathematical expression or context. 2. "Nm" could represent newton-meters, a unit of torque in physics, but without further context, this is uncertain. 3. The numbers "2\n2\n /C\n2\n2" do not form a recognizable mathematical or scientific expression as given. 4. To assist you better, please provide more context or clarify the question or expression you want to understand.
