Answer: [tex]6\sqrt{2x}[/tex]


Step-by-step explanation:

1. You have the following expression given in the problem above:

[tex]4\sqrt{\frac{9x}{2} }[/tex]

2. Remove the perfects squares from the square root:

[tex]9=3^{2}[/tex]

Then:

[tex]4*3\sqrt{\frac{x}{2}}=12\sqrt{\frac{x}{2}}[/tex]

3. Now, rationalize the denominator, because it cotains an square root. Multiply the numerator and the denominator by [tex]\sqrt{2}[/tex] and simplify, as following:

[tex]12\sqrt{\frac{x}{2}}=\frac{12(\sqrt{x})(\sqrt{2})}{(\sqrt{2})(\sqrt{2})}=\frac{12\sqrt{2x}}{(\sqrt{2})^{2}}=\frac{12\sqrt{2x}}{2}=6\sqrt{2x}[/tex]
