Question

\sqrt{18} - \sqrt{50}

Answer 1

Tiana, the question is? :)

Answer 2

\[\large \sqrt{18} - \sqrt{50}\]


\[\large \sqrt{9*2} - \sqrt{25*2}\]


\[\large \sqrt{9}*\sqrt{2} - \sqrt{25}*\sqrt{2}\]


\[\large 3*\sqrt{2} - 5*\sqrt{2}\]


\[\large (3 - 5)*\sqrt{2}\]


\[\large -2\sqrt{2}\]


=======================================================

Therefore,


\[\large \sqrt{18} - \sqrt{50} = -2\sqrt{2}\]
