Given,

\[\left( {\sqrt 5  + 3} \right)\left( {\sqrt 5  + 7} \right)\]

Solution,

\[\begin{array}{l} = \left( {\sqrt 5  + 3} \right)\left( {\sqrt 5  + 7} \right)\\ = \sqrt 5  \times \sqrt 5  + \sqrt 5  \times 7 + 3 \times \sqrt 5  + 3 \times 7\\ = 5 + 7\sqrt 5  + 3\sqrt 5  + 21\\ = 26 + 10\sqrt 5 \end{array}\]

Hence the value is \[26 + 10\sqrt 5 \]
