If ln a=2,ln b=3, and ln c=5 evaluate the following

Question

ln(a-1/b4c-2)= ln square root of b to the 3rd power c to the 2nd power a to the 3rd power= ln(a to the negative 4th power b to the negative 1 power /ln(bc) to the negative 2nd power (ln c to the negative 3rd power)(ln a/b to the negative 2nd power)=
