  1. I assume you meant
    √(21x) , and not the way you typed

    since 21 = 3x7 , you want either another 3 or 7 in x so that we have at least one perfect square.
    none of the first 3 choices contain a 3 or 7 ,but 54 does
    so √(21x54)
    = √3x7x3x9x2)
    = √(81*14)
    = 9√14

    do the other one the same way
