simplify
263*2/4^4+3^4
266/256+81
20/337
1252*5/3^3/3^2(3)^2
12510/27/9(9)
115/39
115/27

aside from the ambiguity caused by a paucity of parentheses,
#1 looks ok
#2 (3)^2 = 9, not 9
but that's ok, since you dropped it in the next step anyway.Other than that, it's virtually incomprehnsible.
Add some parens so it's clear what is wanted. I can guarantee that 115/39 is not 115/27, no matter how you parse it.
