Given,
⇒x=log3 27=log10 27log10 3=log10 33log10 312=3log10 312log10 3=312=3×2=6.\Rightarrow x = \text{log}{\sqrt{3}} \space 27 \\[1em] = \dfrac{\text{log}{10} \space 27}{\text{log}{10} \space \sqrt{3}} \\[1em] = \dfrac{\text{log}{10} \space 3^3}{\text{log}{10} \space 3^{\dfrac{1}{2}}} \\[1em] = \dfrac{3\text{log}{10} \space 3}{\dfrac{1}{2}\text{log}_{10} \space 3} \\[1em] = \dfrac{3}{\dfrac{1}{2}} \\[1em] = 3 \times 2 = 6.⇒x=log3 27=log10 3log10 27=log10 321log10 33=21log10 33log10 3=213=3×2=6.
Hence, Option 3 is the correct option.

Solve for x:
log3 x + log9 x + log81 x = 74\dfrac{7}{4}47
log2 x + log8 x + log32 x = 2315\dfrac{23}{15}1523
If log5 (0.04) = x, then the value of x is
2
-4
-2
If log0.5 64 = x, then the value of x is
-6
