Question

(5+√5) (5-√5) with this formal √a√b= √ab​

Answer 1

Answer:

$(\sqrt{5 + \sqrt{5} } )( \sqrt{5 - \sqrt{5} } ) = \sqrt{(5 + \sqrt{5} )(5 - \sqrt{5} )} \\ \\ \\ = > \sqrt{ {5}^{2} - \sqrt{5} ^{2} } \\ \\ = > \sqrt{25 - 5} \\ \\ = > \sqrt{20} \\ \\ = > \sqrt{5 \times 4} \\ \\ \\ = > 2 \sqrt{5}$
