Sorry i'm knew to this website? I'm not sure how do you show me the steps? I really need to learn its just a review for me! Sorry about that ~ Thanks though!

Alright, np, I'll show you it.

Answer 4

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

\[\sqrt{18} = \sqrt{2\times3^3} = 3\sqrt{2}\]
\[\sqrt{50}=\sqrt{2\times5^2}=5\sqrt{2}\]

\[3\sqrt{2}-5\sqrt{2} \implies -2\sqrt{2}\]

Answer 5

that should be a 3^2 not 3^3
