1)

The value of $log_{2\sqrt{3}}(1728)$ is :


A) 5

B) 3

C) 9

D) 6

Answer:

Option D

Explanation:

Let $log_{2\sqrt{3}}(1728)$ $=x$.

Then, $(2\sqrt{3})^{x}$ $=1728$

$=(12)^{3}$ $=\left[\left(2\sqrt{3}\right)^{2}\right]^{3}$

$=(2\sqrt{3})^{6}$.

$\therefore x=6$

i.e., $log_{2\sqrt{3}}(1728)$ = 6.
