Answer 2

HEY FRIEND...!!!
♪♥HERE IS YOUR ANSWER♥♪
$(2 \sqrt{45} + 3 \sqrt{20}) / 2 \sqrt{5} \\ = (2 \sqrt{9 \times 5} + 3 \sqrt{4 \times 5}) /2 \sqrt{5} \\ = (2 \sqrt{ {3}^{2} \times5 } + 3 \sqrt{ {2}^{2} \times 5 }) 2 \sqrt{5} \\ = (6 \sqrt{5} + 6 \sqrt{5} )/ 2 \sqrt{5} \\ = 12 \sqrt{5} /2\sqrt{5}$
=6
So the answer is rational...

I HOPE IT HELPS YOU...!!!
