Hey Jaywadmare, the anwer of your question is 34/3.

Also go through following explanation.

Explanation : a^2 = d ^12

b^3 = d ^12

c^9 = d ^12

after that logd ( d^12) 1/2 + 1/3 + 1/9 = logd (d^12)^ 51/54

= logd (d ^12 * 17/18)

= 1 * 12 * 17/18

= 34/3.

I hope this will helps to you and thank you !!!
