    To rationalize the denominator, multiply by√5/√5 (which is 1).

    15√6 (√5)

    3√5 (√5)

    This makes the √5 in the denominator 5.

    15√6√5

    3 (5)

    Multiply the √6 and √5 to get√30, which cannot be simplified, so you get

    15√30

    15

    15/15 simplifies to 1, so the final answer is √30
