\( 8 \times 9 - [ 32 - \{ 24 \div ( 8 - \overline { 4 - 2 } ) \} ] \)

Simplify the expression. \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}} \) \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}}=0.021922 \) (Round to the nearest thousandth.)

Simplify the expression. \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}} \) \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}}=\square \) (Round to the nearest thousandth.)

Find, if possible, \( A B \) and \( B A \). If it is not possible, explain why. \[ A=\left[\begin{array}{rr}-4 & 4 \\ 0 & 1\end{array}\right] \quad B=\left[\begin{array}{rrrr}-5 & 0 & 4 & 1 \\ 3 & 0 & 1 & 9\end{array}\right] \]

f) \( \sqrt[8]{3^{32}} \)

e) \( \sqrt{1+\frac{9}{16}}= \)
