\[f[x] \text{=} 0.117*x{}^{\wedge}1.7 \] Rewrite the equation with rationalized decimal numbers and simplify \[f[x]==\frac{117 x^{17/10}}{1000} \] \[f[68]==\frac{1989}{125} 2^{2/5} 17^{7/10}=152.6 \] \[\text{Solve}\left[\frac{117 x^{17/10}}{1000}=185,x\right], x=\frac{50\ 2^{13/17} 5^{6/17} 37^{10/17}}{3\ 3^{3/17} 13^{10/17}}=76.2\] Solved with Mathematica 8.
