SOLUTION: Please help me answer this, Thank you so much! If x= {{{sqrt(7)+sqrt(3)}}}/{{{sqrt(7)-sqrt(3)}}} and y={{{sqrt(7)-sqrt(3)}}}/{{{sqrt(7)+sqrt(3)}}} then evaluate the following qu

Question 982481: Please help me answer this, Thank you so much!
If x= / and y=/
then evaluate the following questions:
1) y/x+x/y
2) x^2/y+y^2/x

Using them, find what happens if substitute for question (1).

The next two steps are difficult to give through the keyboard and text and I omit them here; involving "invert and multiply" for the complex fractions and of multiplying binomials;

but then you can show the step

, which is reducible

Next, the process of rationalizing the denominators will also act to raise each rational expression to higher terms having the common denominator.

, and you have the result causing Difference of Squares for the denominators. (NOTE that this step is now fixed...)

The rest of the arithmetic steps should be expected without overly-strategizing.
