Question

16x⁴-2=0 respondam por favor.

Answer 1

Oie, Td Bom?!

$16x {}^{4} - 2 = 0$

$16x {}^{4} = 2$

$x {}^{4} = \frac{2}{16}$

$x {}^{4} = \frac{1}{8}$

$x = ± \sqrt[4]{ \frac{1}{8} }$

$x = ± \frac{ \sqrt[4]{2} }{2}$

$S = \left \{ - \frac{ \sqrt[4]{2} }{2} \:, \: \frac{ \sqrt[4]{2} }{2} \right \}$
