## anonymous 3 years ago Ok for example if i have the problem square root(180) plus square root(180) Do i add the 180 together to 360. Or do I simplify first and then add the fives that results in the radical. Or do I just leave 180 as it is which would then make it 2 squareroot(180)

$\sqrt{180}+\sqrt{180}$

$\sqrt{180}+\sqrt{180} \ne \sqrt{360}$Just let $$a=\sqrt{180}$$, then you get a+a for your question, which becomes 2a. So, you get $$2\sqrt{180}$$. But that's not the end of the story. You can still simplify $$\sqrt{180}$$ as $$\sqrt{180}=\sqrt{9\times 4 \times 5}=\sqrt{6^2\times5}$$
