You asked:

Evaluate the expression: \(\frac{{20}^{2}}{2} \cdot 9.8\)

MathBot Answer:

\[\frac{{20}^{2}}{2} \cdot 9.8 = 1960\]

\[\begin{aligned}\frac{{20}^{2}}{2} \cdot 9.8& = 20^{2} \cdot \frac{1}{2} \cdot \left(9 + \frac{8}{10}\right)\\& = \frac{400}{2} \cdot \left(9 + \frac{8}{10}\right)\\& = \frac{400}{2} \cdot \left(9 + \frac{4}{5}\right)\\& = \frac{400}{2} \cdot \frac{49}{5}\\& = 200 \cdot \frac{49}{5}\\& = 1960\end{aligned}\]
