26-3*2/4^4+3^4

26-6/256+81

20/337

125-2*5/3^3/3^2-(-3)^2

125-10/27/9-(-9)

115/3-9

115/27

want to know if these two problem right

**Steve**, Monday, October 3, 2011 at 10:32amaside 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 115/3-9 is not 115/27, no matter how you parse it.

algebra - simplify 26-3*2/4^4+3^4 26-6/256+81 20/337 125-2*5/3^3/3^2-(-3)^2 125-...
