So, we have \(\dfrac{\sqrt{180}+\sqrt{45}}{\sqrt{135}}\)

\(=> \dfrac{\sqrt{36*5}+\sqrt{9*5}}{\sqrt{15*9}}\)

\(=> \dfrac{6\sqrt{5}+3\sqrt{5}}{3\sqrt{15}}\)

\(=> \dfrac{9\sqrt{5}}{3\sqrt{15}}\)

\(=> \dfrac{3\sqrt{5}}{\sqrt{3*5}}\)

\(=> \dfrac{3\sqrt{5}}{\sqrt{3}\times \sqrt{5}}\)

\(=> \sqrt{3}\)

Correct answer: A

Hope this helps!

Solution:

Simplifying the expression, we have:

(√36√5 + √9√5) / (√9√3√5)

(6√5 + 3√5) / (3√3√5)

9/(3√3)

3/√3

√3

Answer: A
