Answer 1

Explicación paso a paso:

${5}^{x + 2} + {5}^{x + 1} = 30$

${5}^{x} \times {5}^{2} + {5}^{x} \times 5 = 5 \times 6$

${5}^{x} ( {5}^{2} + 5) = 5 \times 6$

${5}^{x} (25 + 5) = 5 \times 6$

$\frac{{5}^{x} (30)}{6} = 5$

${5}^{x} \times 5 = 5$

${5}^{x + 1} = 5$

$x + 1 = 1$

$x = 1 - 1$

$x = 0$
