simplify write the answers with all exponents positive
You didn't put any parentheses to show where numerator
and denominator begin and end, so I can't tell whether
you mean
or whether you mean
-----------------------------------
If it's the first way
Use the rule: = to rewrite
all the terms in numerator and denominator
Now we can erase all the 1 exponents:
Now look at all the denominators in the main
numerator and the main denominator. They are
x, y and y. The LCD is then xy, so we multiply
by but write it as·
Now distribute the in the numerator
and indicate the multiplication of the denominators
Cancel the x's in the first term on top, and just get y
Cancel the y's in the second term on top, and just get x
and cancel the x's in the term on the bottom, and just get y
So the answer is just
