I can only think of printing it using fprintf():
fprintf('1/%d^2 ',x)

fprintf('1/%d^2 ',x.^2) shows 1/4 1/9 1/16 1/25 not 1/2^2 , 1/3^2, 1/4^2.what I need is the 1/x^2 one .

But
fprintf('1/%d^2 ',x.^2)
is not what was proposed, but rather
fprintf('1/%d^2 ',x)

You can also create symbolic numbers
sym(1/3)
1/3
but be mindful that all calculations you do with such numbers will also give symbolic results only.
