Answer 1

Explicação passo-a-passo:

5.

$f(x) = {25}^{x + 1} = > \sqrt{5} =( {5}^{2} ) {}^{x + 1} = > {5}^{ \frac{1}{2} } = {5}^{2x + 2} = > {5}^{ - 2} = {5}^{2x + 2} = > - 2 = 2x + 2 = > - 2 = 2x + 2 = > - 2 - 2 = 2x = > - 4 = 2x = > - \frac{4}{2} = x = > - 2 = x$

6.

${121}^{2x - 8} = 1 = > ( {11}^{2} ) {}^{2x - 8} = {11}^{0 } = > {11}^{4x - 16} = {11}^{0} = > 4x - 16 = 0 = > 4x = 16 = > x = \frac{16}{4} = > x = 4$
