Answer 1

Explicación paso a paso:

$1) {7}^{x} ( {7}^{2} - 7 + 1) = 43 \\ {7}^{x} (43) = 43 \\ {7}^{x} = 1 \\ x = 0$

$2){2}^{x} (1 + {2}^{2} ) = 5 \\ {2}^{x} (5) = 5 \\ \times = 0$

${ \frac{1}{2} }^{x} (1 - 3( { \frac{1}{2} }^{ - 2} ) = - 22 \\ { \frac{1}{2} }^{x} ( - 11) = - 22 \\ { \frac{1}{2} }^{x} = 2 \\ x = - 1$
