    For your problems we have:

    √2(x + √7)

    (x • √2) + (√7 • √2)

    x√2 + √14 (<==Answer)

    Similarly,

    √6(7 - √6)

    (7 • √6) - (√6 • √6)

    7√6 - √36 (since 36 has a Square Root, we get:)

    7√6 - 6 (<==Answer)

    √2(x + √7)

    = √2 × x + √2 × √7)

    = √2 x + √14

    √6(7 – √6)

    √6 × 7 – √6 √6

    7 √6 – √36

    7 √6 – 6
