    Rationalize the denominator: 7/(7 - (square root of)7)
=[7*{7+SQRT(7)}]/[{7-SQRT(7)}{7+SQRT(7)}]
=[7*{7+SQRT(7)}]/[7^2-{SQRT(7)}^2]
=[7*{7+SQRT(7)}]/(49-7)
=[7+SQRT(7)]/6

    a) (square root of)7
    b) 7 + (square root of)7
    c) (7 + (square root of)7)/6...............CORRECT
    d) (7 + (square root of)7/42
    e) None of these</PRE>
