### Quick Computation

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

Hi;

Is this what you want?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
