Question

me ayudan porfavor
se los agradecería muchísimo ​

Answer 1

Explicación paso a paso:

a)

${x}^{2} = 9 \\ x = \sqrt{9} \\ x = 3$

b)

$23x = 38 \\ x = \frac{38}{23}$

c)

$9 {x}^{3} = 30 \\ {x}^{3} = \frac{30}{9} \\ x = \sqrt[3]{ \frac{10}{3} }$

d)

${x}^{4} = 6x \\ \frac{ {x}^{4} }{x} = 6 \\ {x}^{3} = 6 \\ x = \sqrt[3]{6}$

e)

$8x = 4 {x}^{3} \\ \frac{8}{4} = \frac{ {x}^{3} }{x} \\ 2 = {x}^{2} \\ \sqrt{2} = x$

f)

$2 {x}^{3} = 12x \\ \frac{ {x}^{3} }{x} = \frac{12}{2} \\ {x}^{2} = 6 \\ x = \sqrt{6}$
