    Hey, could you draw out the equation? Or use the equation editor? That would help anyone trying to intepret what you are asking quicker.

    \[8\sqrt{v ^{2}} - \sqrt{v ^{4}} - \sqrt{9v ^{2}} + \sqrt{16v ^{4}}\] simplified

    \(\sqrt{v^{4}} = v^{2}\) \(\sqrt{v^{2}} = |v|\)

    @tkhunny Okay so that would be the simplified term for the second term then? what about the fourth term? how should I simplify it?

    ...except for the fact that the first term is incorrect unless we have the additional information that \(v \ge 0\).
