Explanation
| $$ \begin{aligned}\frac{4.5^2\sqrt{204.75}}{3}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{16\cdot2\sqrt{51}}{3} \xlongequal{ } \\[1 em] & \xlongequal{ }\frac{32\sqrt{51}}{3}\end{aligned} $$ | |
| ① | $$ \sqrt{204} =
\sqrt{ 2 ^2 \cdot 51 } =
\sqrt{ 2 ^2 } \, \sqrt{ 51 } =
2 \sqrt{ 51 }$$ |
