    first substitute a for log x and b for log y made it easier for me using method 2.

    I don't know if it includes all the possible solutions, but at a first glance sqrt(54) is sqrt(2) × sqrt(27).
    in other words:
    2^l1 × 3^l2 = 2^ (0.5) × 3^(1.5)
    and isolating terms:
    2^l1 = 2^(0.5)
    3^l2 = 3^(1.5)
    so: l1 = 0.5 l2 = 1.5
    And sure indeed l1 + l2 = 2
    x = sqrt(10)
    y = sqrt(1000)

    I simply looked at 54 and remembered 9 x 6 is 54.
    1. The root is 3 x root(3)root(2).
    2. Equating the powers of the primes, 2^log(x) = root(2) giving log(x) = 1/2, and 3^log(y) = 3 root(3) giving log(y) = 3/2. Given 1/2 + 3/2 = 2, log(x) + log(y) = 2.
    3. The values of x, y are root(10) and 10 root(10) respectively.
