    Answer:

    3\sqrt{7}

    Step-by-step explanation:

    Take 2 factors of 63 (the bigger the number the less you have to do):

                                                        \sqrt{63}

                                                    9             7

    (The numbers 9 and 7 both multiply into 63)

    So, now break it down even more since 9 is a perfect square:

                                                        \sqrt{63}

                                                    9             7

                                              3          3

    Now that you have two 3’s, you put that outside of the radical and keep the 7 inside:

    3\sqrt{7}

    Answer:

     \sqrt{63} =\sqrt{9\times7} =  \sqrt{3 \times 3 \times 7} = 3 \sqrt{7}

    3√7 is the right answer.
