To rationalize the below,
[tex]\frac{5}{\sqrt[]{3}}[/tex]You'll multiply both the numerator and denominator by the denominator to eliminate the square root sign,
Rationalizing the denominator,
[tex]=\frac{5}{\sqrt[]{3}}\times\frac{\sqrt[]{3}}{\sqrt[]{3}}=\frac{5\times\sqrt[]{3}}{\sqrt[]{3}\times\sqrt[]{3}}=\frac{5\sqrt[]{3}}{3}[/tex]To be written in the form below,
[tex]\begin{gathered} \frac{A}{B}=\frac{5\sqrt[]{3}}{3} \\ A=5\sqrt[]{3} \\ B=3 \end{gathered}[/tex]Hence, A and B are deduced below.
