To fully simplify the given expression, we need to follow the order of operations (PEMDAS).
Starting with the exponentiation, we have:
3^3 = 3 ร 3 ร 3 = 27
Now let's simplify the rest of the expression:
20 + 27 + 0 รท 2
Since division takes precedence over addition, we solve the division first:
0 รท 2 = 0
Now we have:
20 + 27 + 0
Adding the numbers together gives:
47 + 0
Finally, the simplified expression is:
47
