Question

Alguien me da una mano?

Answer 1

a)
$\frac{ - 23 }{4} + x ^{2} = \frac{1}{2}$
$x ^{2} = \frac{1}{2} + \frac{23}{4}$
$x ^{2} = \frac{25}{1}$
$\sqrt{ {x}^{2} } = \sqrt{ \frac{25}{4} }$
$x = + \frac{5}{2}$
Y
$x = - \frac{5}{2}$

b)
$\frac{5}{3} + \sqrt{x } = \frac{13}{6}$
$\sqrt{x} = \frac{13}{6} - \frac{5}{3}$
$\sqrt{x} = \sqrt{\frac{1}{2} }$
$x = 0.70$
Y
$x = - 0.70$

c)
$\frac{19}{27} + \frac{1}{5} {x}^{3} = - \frac{ 2}{9}$
${x}^{3} = - \frac{125}{27}$
$x = - \frac{5}{3}$


d)
3x^4-7/16= -1/4
x^4=1/16
x=1/2 Y x=-1/2

e)
raiz ((1/2)x)-5/4=-11/12
x=2/9

f)
3/243+(x-1/2)^5= 1/81
x= 5/6
