解答ステップ

62831.85 (\frac{1}{5088})^{\frac{1}{4}}

(\frac{1}{5088})^{\frac{1}{4}} = \frac{1}{2 \cdot 31 8 ^{\frac{1}{4}}}

= 62831.85 \cdot \frac{1}{2 \cdot 31 8 ^{\frac{1}{4}}}

分数を乗じる:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 62831.85}{2 \cdot 31 8 ^{\frac{1}{4}}}

数を乗じる:

1 \cdot 62831.85 = 62831.85

= \frac{62831.85}{2 \cdot 31 8 ^{\frac{1}{4}}}

元を10進法形式に変換する

31 8^{\frac{1}{4}} = 4.22286 \dots

= \frac{62831.85}{2 \cdot 4.22286 \dots}

数を乗じる:

2 \cdot 4.22286 \dots = 8.44572 \dots

= \frac{62831.85}{8.44572 \dots}

数を割る:

\frac{62831.85}{8.44572 \dots} = 7439.48840 \dots

= 7439.48840 \dots
