[tex]\ Use \ Product \ Rule[/tex] [tex]x^ax^b=x^a^+^b[/tex]
[tex]2x^3n^2=54[/tex]
[tex]x^3n^2= \dfrac{54}{2} [/tex] [tex]\ Divide \ both \ sides \ by \ 2[/tex]
[tex]x^3n^2=27
[/tex]
[tex]n^2= \dfrac{27}{x^3} [/tex] [tex]\ Divide \ both \ sides \ by \ x^3[/tex]
[tex]n=+ \sqrt{ \dfrac{27}{x^3}} [/tex] [tex] \ Take \ the \ square \ root \ of \ both \ sides[/tex]

[tex]If \ you \ mean \ 2x*3xnxn=54 . \ Lets \ Solve \ for \ n[/tex]
[tex]2x*3xnxn=54[/tex]
[tex]6x^3n^2=54
[/tex]
[tex]x^3n^2= \dfrac{54}{6} [/tex] [tex]\ Divide \ both \ sides \ by \ 6[/tex]
[tex]x^3n^2=9
