Question

$$3(2x)^{4}=81$$

Solve for x (complex solution)

$x=\frac{3^{\frac{3}{4}}i}{2}\approx 1.139753528i$
$x = \frac{3 ^ {\frac{3}{4}}}{2} \approx 1.139753528$
$x = -\frac{3 ^ {\frac{3}{4}}}{2} \approx -1.139753528$
$x=-\frac{3^{\frac{3}{4}}i}{2}\approx -0-1.139753528i$

Solve for x

$x = \frac{3 ^ {\frac{3}{4}}}{2} \approx 1.139753528$
$x = -\frac{3 ^ {\frac{3}{4}}}{2} \approx -1.139753528$
