    27^radical 5 x 9^ radical 5

    27^rt(5)*9^rt(5)

    [27*9]^rt(5)

    [{3}^3*{3}^2]^rt(5)

    [{3}^5]^rt(5)

    3

    (x^a)^rt(a)=x

    using this above only we get 3

    27^(sqrt(5)) * 9^(sqrt(5))

    27 = 3^3

    9 = 3^2

    27^(sqrt(5)) = (3^3)^(sqrt(5)) = 3^(3 sqrt(5))

    9^(sqrt(5)) = (3^2)^(sqrt(5)) = 3^(2 sqrt(5))

    27^(sqrt(5)) * 9^(sqrt(5)) = 3^(3 sqrt(5)) 3^(2 sqrt(5))

    = 3^(3 sqrt(5) + 2 sqrt(5))

    = 3^(5 sqrt(5))
