Question

Evaluar, urgente para hoy !! Ayúdenme jiji

Answer 1

Respuesta:

E) 20

Explicación paso a paso:

${5}^{ - x} = \frac{1}{2}$

${5}^{ - x} = {2}^{ - 1}$

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

${5}^{x} = 2$

evalúe:

$P = 125^x + 625^x -25^x$

$P = ( {5}^{3}) ^x + ( {5}^{4} )^x - {(5}^{2}) ^x$

$P = ( {5}^{x}) ^3+ ( {5}^{x} )^4 - {(5}^{x}) ^2$

$P = (2) ^3+ (2)^4 - (2) ^2$

$P = 8+ 16- 4$

$P = 20$
