does anyone know, why do I keep getting this error message?
!You cant use '\eqno' in math mode.
..and it's pointing at this line in my code:
\left(\sqrt[5]{x^4}\right)’ &=& \left(x^{[\frac{4}{5}\]}\right)’ &=& [\frac{4}{5}\]x^{[-\frac{1}{5}\]} &=& [\frac{4}{5\sqrt[5]{x}\}] \label{rovnice3} \\
here's the whole array:
\begin{eqnarray}
\int_a^b f(x)\,\mathrm{d}x &=& -\int\limits_b^a f(x)\,\mathrm{d}x \label{rovnice2}\\
\left(\sqrt[5]{x^4}\right)’ &=& \left(x^{[\frac{4}{5}\]}\right)’ &=& [\frac{4}{5}\]x^{[-\frac{1}{5}\]} &=& [\frac{4}{5\sqrt[5]{x}\}] \label{rovnice3} \\ \overline{\overline{A \lor B}} &=& \overline{\overline{A} \land \overline{B}\label{rovnice4} \end{eqnarray}
Thanks in advance!

If you want to answer I'll delete mine, or I'll add that to mine,
