0.2k^{1/3}=0.062k

解

0.2 k^{\frac{1}{3}} = 0.062 k

解

k = 0, k = - (\frac{0.008}{0.000238328})^{\frac{1}{2}}, k = (\frac{0.008}{0.000238328})^{\frac{1}{2}}

+1

十進法表記

k = 0, k = - 5.79371 \dots, k = 5.79371 \dots

解答ステップ

0.2 k^{\frac{1}{3}} = 0.062 k

equationの両辺を以下の累乗にする:

3 : 0.008 k = 0.000238328 k^{3}

0.008 k = 0.000238328 k^{3}

解く

0.008 k = 0.000238328 k^{3} : k = 0, k = - (\frac{0.008}{0.000238328})^{\frac{1}{2}}, k = (\frac{0.008}{0.000238328})^{\frac{1}{2}}

k = 0, k = - (\frac{0.008}{0.000238328})^{\frac{1}{2}}, k = (\frac{0.008}{0.000238328})^{\frac{1}{2}}

解を検算する:

k = 0

真

, k = - (\frac{0.008}{0.000238328})^{\frac{1}{2}}

真

, k = (\frac{0.008}{0.000238328})^{\frac{1}{2}}

真

解答は

k = 0, k = - (\frac{0.008}{0.000238328})^{\frac{1}{2}}, k = (\frac{0.008}{0.000238328})^{\frac{1}{2}}
