Question

ayuda porfavor no entiendo

Answer 1

Explicación paso a paso:

${2}^{ {3}^{3x - 4} } = 512$

${2}^{ {3}^{3x - 4} } = {2}^{9}$

${2}^{ {3}^{3x - 4} } = {2}^{ {3}^{2} }$

${{3x - 4} } = 2$

$3x = 2 + 4$

$3x = 6$

$x = \frac{6}{3}$

$x = 2$

Comprobación

${2}^{ {3}^{3x - 4} } = 512$

${2}^{ {3}^{3(2) - 4} } = 512$

${2}^{ {3}^{6- 4} } = 512$

${2}^{ {3}^{2} } = 512$

${2}^{ {9} } = 512$

$512 = 512$
