    Answer:

    the value of x+y is 26.

    Step-by-step explanation:

    x={(√7–√6)/(√7+√6)}×{(√7–√6)/(√7–√6)}

    =(√7–√6)²/{(√7)²-(√6)²}

    =(7+6–2√42)/(7–6)= (13–2√42)

    y={(√7+√6)/(√7–√6)}×{(√7+√6)/(√7+√6)}

    =(√7+√6)²/{(√7)²-(√6)²}

    =(7+6+2√42)/(7–6)= (13+2√42)

    Now,

    x+y= 13-2√42+13+2√42

    = 13+13

    = 26..

    Please mark my answer as a brainleast.......
