Answer:

Option C. [tex]ln(\frac{2x^{3}}{3y})[/tex]

Step-by-step explanation:

The given logarithmic expression is:

[tex]ln(2x)+2ln(x)-ln(3y)[/tex]

Using the power rule of logarithms: [tex]blog(a)=log(b)^{a}[/tex], the above expression can be written as:

[tex]ln(2x)+ln(x)^{2}-ln(3y)[/tex]

Using the product rule of logarithms: [tex]log(a)+log(b) =log(ab)[/tex], the above expression can be simplified further to:

[tex]ln(2x \times x^{2}) - ln(3y)\\\\=ln(2x^{3})- ln(3y)[/tex]

Using the quotient rule of logarithms: [tex]log(a)-log(b)=log(\frac{a}{b})[/tex], the above expression can be written as:

[tex]ln(\frac{2x^{3}}{3y})[/tex]

Hence option C gives the correct simplified answer.
