Question

simplify

Answer 1

\[4\sqrt{n^2}+\sqrt{m^2n}-\sqrt{4n^2}-\sqrt{mn^2}\]

Answer 2

i got 2n+\[m \sqrt{n}-\sqrt{m}\]

Answer 3

almost right the last part should be
\[ \large n\sqrt{m} \]

Answer 4

\[ 4\sqrt{n^2}+\sqrt{m^2n} -\sqrt{4n^2}-\sqrt{mn^2}\]
\[ 4n+m\sqrt{mn} -2n-n\sqrt{mn}\]
\[ 2n + (m-n)\sqrt{mn} \]
