v^4-0.8949v^2+0.028367=0

解

v^{4} - 0.8949 v^{2} + 0.028367 = 0

解

v = \frac{8949 + 11 568081}{100 2}, v = - \frac{8949 + 11 568081}{100 2}, v = \frac{8949 - 11 568081}{100 2}, v = - \frac{8949 - 11 568081}{100 2}

+1

十進法表記

v = 0.92843 \dots, v = - 0.92843 \dots, v = 0.18140 \dots, v = - 0.18140 \dots

解答ステップ

v^{4} - 0.8949 v^{2} + 0.028367 = 0

equationを

u = v^{2}

と以下で書き換える:

u^{2} = v^{4}

u^{2} - 0.8949 u + 0.028367 = 0

解く

u^{2} - 0.8949 u + 0.028367 = 0 : u = \frac{0.8949 + 0.68737801}{2}, u = \frac{0.8949 - 0.68737801}{2}

u = \frac{0.8949 + 0.68737801}{2}, u = \frac{0.8949 - 0.68737801}{2}

再び

u = v^{2}

に置き換えて以下を解く:

v

解く

v^{2} = \frac{0.8949 + 0.68737801}{2} : v = \frac{8949 + 11 568081}{100 2}, v = - \frac{8949 + 11 568081}{100 2}

解く

v^{2} = \frac{0.8949 - 0.68737801}{2} : v = \frac{8949 - 11 568081}{100 2}, v = - \frac{8949 - 11 568081}{100 2}

解答は

v = \frac{8949 + 11 568081}{100 2}, v = - \frac{8949 + 11 568081}{100 2}, v = \frac{8949 - 11 568081}{100 2}, v = - \frac{8949 - 11 568081}{100 2}
