The way you typed it, none of these answers are correct,
BUT
if you mean
5/(√7 - √2) then
5/(√7 - √2)
=5/(√7 - √2) * (√7+√2)/(√7+√™)
= (5√7 + 5√2)/5
= √7 + √2
im truly sorry because i cant get how to write these square root correctly. but yes that what i meant the way yo wrote it and thanks so much for your help reiny. :)
