Question

Simplify 7 radical 3 + 8 radical 3 - 2 radical 2

Answer 1

There's a property of radicals.

\(\Large \color{Orange}{\Rightarrow x\sqrt{a} + y\sqrt{a} = (x + y)\sqrt{a} }\)

Answer 2

Similarly,

\(\Large \color{Orange}{\Rightarrow 7\sqrt{3} + 8\sqrt{3} = (8 + 7)\sqrt{3} = 15\sqrt{3} }\)

Answer 3

That just leaves \(15\sqrt{3} - 2\sqrt{2}\).
