Question

Simplify 2 radical 7 - 4 radical 3

Answer 1

`2(\sqrt[]{7}-2\sqrt[]{3})`

Step-by-step explanation:

Since the radicals are different, the only thing to do is to write 4 as 2*2 and put 2 in evidence:

`\begin{gathered} 2\sqrt[]{7}-4\sqrt[]{3} \\ =2\sqrt[]{7}-2\cdot2\sqrt[]{3} \\ =2(\sqrt[]{7}-2\sqrt[]{3)} \end{gathered}`
