Given the following expression
[tex]\begin{gathered} \sqrt[]{50}\text{ - }\sqrt[]{2} \\ \sqrt[]{50}\text{ can be express as }\sqrt[]{25\text{ x 2}} \\ \text{= }\sqrt[]{25\text{ x 2}}\text{ - }\sqrt[]{2} \\ =\text{ }\sqrt[]{25}\text{ x }\sqrt[]{2}\text{ - }\sqrt[]{2} \\ =5\sqrt[]{2}\text{ - }\sqrt[]{2} \\ =\text{ 4}\sqrt[]{2} \end{gathered}[/tex]-
