Question 1162171
<br>
I won't try to guess what "20C2/3L1/3" means....<br>
If there are some exponents in there, it is standard to use "^" (shift-6) to denote exponentiation.<br>
Is "20C2" supposed to be "20C^2"?<br>
Is "3L1/3" supposed to be "3L^(1/3)"?<br>
And if those aren't exponents, you need to explain what they ARE....<br>
