Use the laws of logarithms to rewrite the expression $\displaystyle{\ln\left(\root 5 \of {xy}\right)}$ in a form that does not contain any logarithm of a product, quotient or power. After rewriting, we have $\displaystyle{\ln\left(\root 5 \of {xy}\right)=A\ln\left(x\right)+B\ln\left(y\right)}$ with constants $A$ = and $B$ = .
