What exactly do you want to do here? simplify?

if so (and this is a really clumbsy problem if that is the case), here are the steps.

....l^(2)wx^(2)ex^(6)......................n^(4)o^(6)d*e

..--------------------.........+.........------------------

.............2.......................................n^(3)o^(5)

before doing anything, i realize in the second fracton, i can cancel the entire denominator from the numerator (you know how to do that right?) i see an n^4 in the top and an n^3 in the bottom, so i can divide the bottom into the top, leaving n in the top and 1 in the bottom. a similar thing happens for the o^6 in the top and o^5 in the bottom

......l^(2)wx^(2)ex^(6)..........................n*o*d*e

..= --------------------.........+.........------------------

...............2..............................................1

now i combine the fractons, the lcm is 2

.......l^(2)wx^(2)ex^(6)......+........2(n*o*d*e)

..= --------------------------------------------

.......................................2

now i notice i have an x^2 and an x^6 in a product in the top, so i can combine these by adding the powers to get x^8

.....l^(2)wx^(8)e......+........2(n*o*d*e)

..= ---------------------------------------

.............................2

now i realize e is common to both terms, so i factor it out

.....e[l^(2)wx^(8)......+........2*n*o*d]

..= ---------------------------------------

.............................2

and that's it i suppose, like i said, a real clumbsy problem, unless you wanted to do something other than simplify
