Answer:
[tex]\dfrac{\sqrt3}{4}[/tex]
Step-by-step explanation:
The given expression is :
[tex]x=\dfrac{3}{4\sqrt{3} }[/tex]
Multiplying both numerator and denominator by [tex]\sqrt{3}[/tex],
[tex]x=\dfrac{3}{4\sqrt{3} }\times \dfrac{\sqrt{3} }{\sqrt{3} }\\\\=\dfrac{3\sqrt3}{4\times 3}\\\\=\dfrac{\sqrt3}{4}[/tex]
So, the rationalized form of the given expression is [tex]\dfrac{\sqrt3}{4}[/tex]
