2x^3*n*n=54


\ Use \ Product \ Rule
x^ax^b=x^a^+^b


2x^3n^2=54


x^3n^2= (54)/(2)
\ Divide \ both \ sides \ by \ 2


x^3n^2=27


n^2= (27)/(x^3)
\ Divide \ both \ sides \ by \ x^3


n=+ \sqrt{ (27)/(x^3)}
\ Take \ the \ square \ root \ of \ both \ sides

If \ you \ mean \ 2x*3xnxn=54 . \ Lets \ Solve \ for \ n


2x*3xnxn=54


6x^3n^2=54


x^3n^2= (54)/(6)
\ Divide \ both \ sides \ by \ 6


x^3n^2=9


n^2= (9)/(x^3)
\ Divide \ both \ sides \ by \ x^3


n=+ \sqrt{ (9)/(x^3) }
\ Take \ the \ square \ root \ of \ both \ sides

It would be
2x3xnxn
N has a 1 in front of it it's just not shown
So
2x3x1nx1n then you'd at as much as possible
5x2n
