The given expression is:
[tex]2\sqrt[]{18x^3}+\sqrt[]{50x}[/tex]
Simplify as follows:
[tex]\begin{gathered} 2\sqrt[]{18x^3}+\sqrt[]{50x}=2\sqrt[]{3\times3\times2\times x^2\times x}+\sqrt[]{5\times5\times2\times x} \\ =2\times3\times x\sqrt[]{2x}+5\sqrt[]{2x} \\ =6x\sqrt[]{2x}+5\sqrt[]{2x} \\ =\sqrt[]{2x}(6x+5) \end{gathered}[/tex]
