The factor tree for 1,764 is shown.
Rashid [163]

Answer:

42

Step-by-step explanation:

               |--------------1764------------|

               |                                      |

              2                           |-------882-----------|

                                           |                            |

                                          2               |--------441------|

                                                           |                      |

                                                   |------9-----|        |----49---|

                                                   |               |        |             |

                                                  3              3      7            7

From the factor tree we see that

1764 = 2^2 \times 3^3 \times 7^2

Now we need to find the square root of 1764.

\sqrt{1764} = \sqrt{2^2 \times 3^2 \times 7^2} = \sqrt{(2 \times 3 \times 7)^2} = \sqrt{(42)^2} = 42
