  • A||

    √32 - 3√2 + √98
    = √16 . √2 - 3√2 + √49 . √2
    = 4√2 - 3√2 + 7√2
    = 8√2

    B||

    5√45 + √80 - 2√125
    = 5 √9 √5 + √16 . √5 - 2 √25 . √5
    = 15 √5 + 4 √5 - 10 √5
    = 9√5

    C||

    5√6 x 2√8 - 8√3
    = 10 √48 - 8√3
    = 10 √16 . √3 - 8 √ 3
    = 40 √3 - 8 √3
    = 32 √3
