Answer:

[tex]a_9=48[/tex]

Step-by-step explanation:

we are given

sequence is geometric

so, we can use nth term formula

[tex]a_n=a_1(r)^{n-1}[/tex]

we have

[tex]a_1=3[/tex]

[tex]r=\sqrt{2}[/tex]

we have to find a9

so, we can plug n=9

we get

[tex]a_9=3(\sqrt{2})^{9-1}[/tex]

[tex]a_9=2^4\cdot \:3[/tex]

[tex]a_9=48[/tex]
