Respuesta:
a) x=3
b) x=250
c) x=81
d) x= -128
Explicación paso a paso:
a)
[tex] \sqrt[x]{24} = 2 \sqrt[x ]{3} \\ \\ {( \sqrt[x]{24}) }^{x} = {(2 \sqrt[x]{3} )}^{x} \\ \\ 24 = {2}^{x} .3 \\ \\ \frac{24}{3} = {2}^{x} \\ \\ 8 = {2}^{x} \\ \\ {2}^{3} = {2}^{x} \\ \\ 3 = x[/tex]
b)
[tex] \sqrt[3]{x} = - 5 \sqrt[3]{2} \\ \\ {( \sqrt[3]{x}) }^{3} = {( - 5 \sqrt[3]{2}) }^{3} \\ \\ x = {( - 5)}^{3} . {( \sqrt[3]{2}) }^{3} \\ \\ x = - 125.2 \\ \\x=-250 [/tex]
c)
[tex] \sqrt[3]{x} = 3 \sqrt[3]{3} \\ \\ {( \sqrt[3]{x}) }^{3} = {(3 \sqrt[3]{3} )}^{3} \\ \\ x = {3}^{3} . {( \sqrt[3]{3}) }^{3} \\ \\ x = 27.3 \\ \\ x = 81[/tex]
d)
[tex] \sqrt[3]{ - x} = 4 \sqrt[3]{2} \\ \\ {( \sqrt[3]{ - x} )}^{3} = {(4 \sqrt[3]{2}) }^{3} \\ \\ - x = {4}^{3} . {( \sqrt[3]{2}) }^{3} \\ \\ - x = 64.2 \\ \\ - x = 1 28 \\ \\ x = - 128[/tex]
