Answer 1

Explicación paso a paso:

$3 {}^{9 {}^{x - 2} } = {27}^{ {9}^{2x + 1} } \\ {3}^{ {9}^{x - 2} } = {3}^{3 \times {9}^{2x + 1} } \\ {9}^{x - 2} = 3 \times {3}^{2(2x + 1)} \\ {9}^{ \times - 2} = {9}^{2(2x + 1)} \\ x - 2 = 2(2x + 1)$

$x - 4x = 4 \\ - 3x = 4 \\ x = - \frac{4}{3}$

$x - 2 = 4x + 2 \\ x = 4x + 4$
