3/2*ln x - lny

Explanation:

ln sqrt(x^3/y^2) can be rewritten as

ln (x^3/y^2)^(1/2)

or ln (x^(3/2)/y^(2/2))

using one of logarithm rules: ln (a/b) = lna - lnb

we have:

ln x^(3/2) - ln y^(2/2)

or ln x^(3/2) - ln y

another one of these rules state that: ln a^b = b*lna

then we have:

3/2*ln x - lny
