Answer 2

Step-by-step explanation:

Given , \bold{\frac{2\sqrt{45}+3\sqrt{20}}{2\sqrt{5}}}25245+320 

\begin{lgathered}\bold{\frac{2\sqrt{45}+3\sqrt{20}}{2\sqrt{5}}} \\\\=\bold{\frac{2\sqrt{3\times3\times5}+3\sqrt{2\times2\times5}}{2\sqrt{5}}}\\\\=\bold{\frac{2.3\sqrt{5}+3.2\sqrt{5}}{2\sqrt{5}}}\\\\=\bold{\frac{12\sqrt{5}}{2\sqrt{5}}}=6\end{lgathered}25245+320=2523×3×5+32×2×5=252.35+3.25=25125=6
