It's been a while and I'm a bit rusty.. I am attempting to rearrange the following equation to make x the subject:

205 = ((4*pi*x*f)/c)^2I have attempted:

205/x^2 = ((4*pi)^2*f^2) / c^2

x^2/205 = c^2/(4*pi)^2*f^2

then

x^2 = 205 * (c^2/((4*pi)^3)*f^2)

x = \sqrt{205*(c^2/((4*pi)^2)*f^2)}

Unfortunately my answer doesn't evaluate. Any tips on my process?

Thanks!
