**drwls**, Saturday, July 5, 2008 at 9:36amUse parentheses to clarify whether you mean

(sqrt r - sqrt s)/ (sqrt r + sqrt s)

or

sqrt r - (sqrt s/ sqrt r) + sqrt s

**Diane**, Saturday, July 5, 2008 at 9:46am(sqrt r- sqrt s)/ sqrt r+ sqrt s)= r sqrt r - sqrt rs + sqrt s/ r

Is the answer I got correct.

**drwls**, Saturday, July 5, 2008 at 11:26amMultiply numerator and denominator by (sqrt r - sqrt s) to get rid of some sqrt signs. The new denominator becomes r-s.

(sqrt r- sqrt s)/(sqrt r+ sqrt s)=

[r - 2 sqrt(rs)+ s]/(r -s)

Your answer is not correct. If you show your work, perhaps we can show you where a mistake was made.
