Question

alguien me ayuda???

la (g) y la (j)

por favor. necesito el paso a paso de los dos​

Answer 1

Verified answer

Explicación paso a paso:

[tex]g) \: ( \frac{2}{3} x - 0.3) ^{2} = \frac{4}{9} [/tex]

[tex] \frac{2}{3} x - 0.3 = + \frac{2}{3} [/tex]

[tex] \frac{2}{3} x - 0.3 = - \frac{2}{3} [/tex]

[tex] \frac{2}{3} x - 0.3 = \frac{2}{3} [/tex]

[tex]x = - \frac{11}{20} [/tex]

[tex]x = \frac{29}{20} [/tex]

[tex]x1 = - \frac{11}{20} \: x2 \: = \frac{29}{20} [/tex]

[tex]j) \: 1.2 + \ \sqrt[3]{1 - x} = \frac{31}{18} [/tex]

[tex] \sqrt[3]{1 - x} = \frac{31}{18} - 1.2[/tex]

[tex] \sqrt[3]{1 - x} = \frac{31}{18} - \frac{6}{5} [/tex]

[tex] \sqrt[3]{1 - x} = \frac{47}{90} [/tex]

[tex]1 - x = \frac{47 ^{3} }{90 ^{3} } - 1[/tex]

[tex]x = - \frac{47 ^{3} }{90 ^{3} } + 1[/tex]

Espero haberte ayudado
