hi all
i have the following error:
  1. ! Extra }, or forgotten \right.

thank you
  1. \begin{align}
  2. \Phi &= \frac{\partial V_{i}}{\partial x_{j}} \tau_{ij}\\
  3. &= \mu \left[ 2 \left( \frac{\partial V_{x}}{\partial x}\right)^{2} +2\left( \frac{\partial V_{y}}{\partial x}\right)^{2} +2\left( \frac{ \partial V_{z}}{ \partial x}\right)^{2} +\left( \frac{ \partial V_{x}}{ \partial x} +\frac{\partial V_{x}}{\partial y}\right)^{2}\\
  4. &+ \left(\frac{\partial V_{z}}{\partial y} +\frac{\partial V_{y}}{ \partial z}\right)^{2} + \left( \frac{\partial V_{x}}{ \partial z} +\frac{\partial V_{z}}{ \partial x}\right)^{2} \left] + \lambda \left(\frac{ \partial V_{x}}{\partial x} +\frac{ \partial V_{y}}{\partial y} +\frac{ \partial V_{z}}{ \partial z} \right)^{2}
  5. \label{eq:mmm}
  6. \end{align}

There are unmatched square brackets: \left[ and \left]. Remove them or make them to a correct \left \right pair.
