(1/(3*2x))^4= 1/16

解

(\frac{1}{3 \cdot 2 x})^{4} = \frac{1}{16}

x = \frac{1}{3}, x = - \frac{1}{3}, x = \frac{1}{3} i, x = - \frac{1}{3} i

解答ステップ

(\frac{1}{3 \cdot 2 x})^{4} = \frac{1}{16}

たすき掛け

16 = 1296 x^{4}

解く

16 = 1296 x^{4} : x = \frac{1}{3}, x = - \frac{1}{3}, x = \frac{1}{3} i, x = - \frac{1}{3} i

x = \frac{1}{3}, x = - \frac{1}{3}, x = \frac{1}{3} i, x = - \frac{1}{3} i
