$\sqrt{50 m} - \sqrt{72 m} = \sqrt{5 \cdot 5 \cdot 2 m} - \sqrt{6 \cdot 6 \cdot 2 m}$ $sqrt(50m)-sqrt(72m) = sqrt(5*5*2m)-sqrt(6*6*2m)$

$= \sqrt{5^{2}} \sqrt{2 m} - \sqrt{6^{2}} \sqrt{2 m}$ $= sqrt(5^2)sqrt(2m)-sqrt(6^2)sqrt(2m)$

$= 5 \sqrt{2 m} - 6 \sqrt{2 m}$ $= 5sqrt(2m)-6sqrt(2m)$

$= (5 - 6) \sqrt{2 m}$ $= (5-6)sqrt(2m)$

$= - \sqrt{2 m}$ $= -sqrt(2m)$
