You asked:

Evaluate the expression: \(\frac{\frac{\frac{22}{7} \cdot 10.5}{2} \cdot 10.5}{2}\)

MathBot Answer:

\[\frac{\frac{\frac{22}{7} \cdot 10.5}{2} \cdot 10.5}{2} = \frac{693}{8} = 86.625\]


\[\begin{aligned}\frac{\frac{\frac{22}{7} \cdot 10.5}{2} \cdot 10.5}{2}& = \frac{22}{7} \cdot \left(10 + \frac{5}{10}\right) \cdot \frac{1}{2} \cdot \left(10 + \frac{5}{10}\right) \cdot \frac{1}{2}\\& = \frac{22}{7} \cdot \left(10 + \frac{1}{2}\right) \cdot \frac{1}{2} \cdot \left(10 + \frac{5}{10}\right) \cdot \frac{1}{2}\\& = \frac{22}{7} \cdot \frac{21}{2} \cdot \frac{1}{2} \cdot \left(10 + \frac{5}{10}\right) \cdot \frac{1}{2}\\& = \frac{22}{7} \cdot \frac{21}{2} \cdot \frac{1}{2} \cdot \left(10 + \frac{1}{2}\right) \cdot \frac{1}{2}\\& = \frac{22}{7} \cdot \frac{21}{2} \cdot \frac{1}{2} \cdot \frac{21}{2} \cdot \frac{1}{2}\\& = \frac{22}{7} \cdot \frac{21}{2} \cdot \frac{1}{2} \cdot \frac{21}{4}\\& = \frac{33}{2} \cdot \frac{21}{4}\\& = \frac{693}{8}\end{aligned}\]
