Answer:
The answer is option 2.
Step-by-step explanation:
You have to apply Logarithm Laws :
[tex] ln( a) - ln(b) ⇒ ln( \frac{ a}{b } ) [/tex]
[tex] ln( {x}^{2} ) ⇒2 ln(x) [/tex]
For this question :
[tex] ln( \frac{ {x}^{2} }{18} ) [/tex]
[tex] = ln( {x}^{2} ) - ln(18) [/tex]
[tex] = 2 ln(x) - ln(18) [/tex]
