How can I solve an equation to find the value of the variable which results zero?

I used the following example:

solve(f/0.0101675799189-72390/{1+3*19/7*(f/324)^{19-1}},f)=#@#


With Mathcad I use the function root which is OK, but I could not make this work in Smath.

By the way the result of variable f should be 294.89241785

Thanks

Use the boolean "=" to set your function equal to zero and then use the 3rd and 4th arguments of the solve function to set the bounds within which to search for the root. See screenshot below:
