Answer:
Option C.
Step-by-step explanation:
The given expression is
[tex]\sqrt{18}[/tex]
We need to find the most simplified form of the given expression.
The given expression can be rewritten as
[tex]\sqrt{2\times 3\times 3}[/tex]
[tex]\sqrt{2\times 3^2}[/tex]
Using the properties of radical expression, we get
[tex]\sqrt{2}\times \sqrt{3^2}[/tex] [tex][\because \sqrt{mn}=\sqrt{m}\sqrt{n}][/tex]
[tex]\sqrt{2}\times 3[/tex]
[tex]3\sqrt{2}[/tex]
Therefore, the correct option is C.
