Question

Determine o valor de X: (Precisa aparecer o cálculo)​​

Answer 1

Resposta:

Explicação passo-a-passo:

c)$(\frac{2}{3} )^{x}=\frac{2^{6} }{3^{6} }$

x=$\frac{6}{6}=1$

d)

$11^{2x} =\frac{1}{14461}$

$11^{2X} =14461^{-1} \\11^{2X} =11^{3^{-1} } \\2X=-3\\X=\frac{-3}{2}$

e)

$2^{x} =\sqrt[3]{256} \\2^{x}=\sqrt[3]{2^{3}*2^{3}*2 } \\2^{x}=4\sqrt[3]{2}\\2^{x}=2^{2}*2^{\frac{1}{3} }\\x=2*\frac{1}{3} \\x=\frac{2}{3}$
