I want to display a lower index within my wolframalpha results (like you see within the attached image, the lB), since I'm not sure how to call this in english I have a hard time searching for the correct syntax in the documentation. I tried the common notations (lB, l_{B}, l[B], l{B},..) but I couldn't get it to work. Does anyone know how the syntax for this is?
Just to be clear, I want to display the B like in the attached png.
Thanks for your help!
