Question

2 root 3 upon root 5 - root 3​

Answer 1

Answer:

√15 + 3

Step-by-step explanation:

(2√3)/ √5 - √3

Rationalizing, we get

 $\frac{2\sqrt{3} }{\sqrt{5}-\sqrt{3} } *\frac{\sqrt{5} + \sqrt{3} }{\sqrt{5} + \sqrt{3} }$

= $\frac{2\sqrt{15} + 6}{5-3}$

= $\frac{2\sqrt{15}+6 }{2}$

= $\sqrt{15} + 3$
