    Answer:

    7 + 2\sqrt{10}

    Step-by-step explanation:

    = (\sqrt{5} + \sqrt{2} )^{2}

    a = \sqrt{5} \\\\b = \sqrt{2}\\\\(a + b)^{2}  = a^{2} +b^{2} + 2ab\\\\

    putting the value of a & b in the equation obtained

    = (\sqrt{5} )^{2} + (\sqrt{2} )^{2} + 2(\sqrt{5})(\sqrt{2} )\\\\= 5 + 2 + 2(\sqrt{10})\\\\= 7 + 2\sqrt{10}
