解

簡約

3^{4} \cdot 2^{- 2} \cdot 4^{2}

324

解答ステップ

3^{4} \cdot 2^{- 2} \cdot 4^{2}

3^{4} = 81

= 81 \cdot 2^{- 2} \cdot 4^{2}

2^{- 2} = \frac{1}{4}

= 81 \cdot \frac{1}{4} \cdot 4^{2}

4^{2} = 16

= 81 \cdot \frac{1}{4} \cdot 16

数を乗じる:

81 \cdot 16 = 1296

= 1296 \cdot \frac{1}{4}

= \frac{1}{4} \cdot 1296

\frac{1}{4} \cdot 1296 = 324

= 324
