Can someone with Mathematica solve

0.0004 = 1.47396x10^-8/x^3+0.238 tan(1.38919x10^-9/((35 x^3)/3+(686000 x)/3))

for me quick? Thanks

Thank you very much. The value was supposed to be real and positive, so either my equation was wrong or the value I entered in Matlab. I've been working on the equation for hours because I thought it was wrong.
