Question

(root 3-root 5)(root 5+root 3/7-2 root 5

Answer 1

Hey dear!


Here is yr answer......


$= > ( \sqrt{3} - \sqrt{5} )( \frac{ \sqrt{5} + \sqrt{3} }{7 - 2 \sqrt{5} } ) \\ \\ = > \frac{ \sqrt{15} - 3 - 5 - \sqrt{15} }{7 - 2 \sqrt{5} } \\ \\ = > \frac{ - 8}{ 7- 2 \sqrt{5} } \\ \\ = > \frac{ - 8}{7 - 2 \sqrt{5} } \times \frac{7 + 2 \sqrt{5} }{ 7+2 \sqrt{5} } \\ \\ = > \frac{ - 56 - 16 \sqrt{5} }{49 - 20} \\ \\ = > \frac{ - 56 - 16 \sqrt{5} }{29}$
Hope it hlpz.
