Answer:
3rd and 4th options
Step-by-step explanation:
Using the rule of exponents
[tex]\frac{a^{m} }{a^{n} }[/tex] ( n > m )
= [tex]\frac{1}{a^{(n-m)} }[/tex]
Then
[tex]3^{4}[/tex] ÷ [tex]3^{9}[/tex]
= [tex]\frac{3^{4} }{3^{9} }[/tex]
= [tex]\frac{1}{3^{(9-4)} }[/tex]
= [tex]\frac{1}{3^{5} }[/tex]
= [tex]\frac{1}{243}[/tex]
