a^2=b^3=c^9=d^12. then log abc to the base d = ??
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 !!!
