f=sqrt((1/(L*C)-(R.^2)/((4*C).^2))); correct way to write the expression in matlab?

We don't know, because we don't know the reference for the expression.

If ‘R’, ‘L’, and ‘C’ are all arrays of the same size, use element-wise operations in every multiplication, division, and exponentiation operation —
f = sqrt((1./(L.*C)-(R.^2)./((4*C).^2)));
See Array vs. Matrix Operations for details.

We can only see, if the expression is written corretly to allow evaluation by MATLAB:
L=1;
C=2;
R=3;
f=sqrt((1/(L*C)-(R.^2)/((4*C).^2)))
f = 0.5995
