Answer:
[tex]3n\cdot 3n[/tex].
Step-by-step explanation:
We have been given an expression [tex](3n)^2[/tex]. We are asked to write our given expression without exponents.
Since 3n is raised to second power, this means that 3n is multiplied by itself.
[tex](3n)^2=3n\cdot 3n[/tex]
Therefore, our required expression would be [tex]3n\cdot 3n[/tex].
