\(\left\{{}\begin{matrix}BB'\perp\left(ABCD\right)\\BB'\in\left(ABB'A'\right)\end{matrix}\right.\) \(\Rightarrow\left(ABCD\right)\perp\left(ABB'A'\right)\)
74.
\(\left\{{}\begin{matrix}DD'\perp\left(ABCD\right)\\DD'\in\left(CDD'C'\right)\end{matrix}\right.\) \(\Rightarrow\left(ABCD\right)\perp\left(CDD'C'\right)\)
b: \(6-3\cdot\left(-\dfrac{1}{3}\right)^3-\sqrt{9}\)
\(=6-3-3\cdot\dfrac{-1}{27}\)
\(=3+\dfrac{1}{9}=\dfrac{28}{9}\)
