Question

verdades equacoes exponenciais 25(x+2)=1

Answer 1

$Propriedade~de~Pot\^encia~ \overrightarrow{~~~~~}~~ Um ~~nu\´mero ~~elevado~~0~~e\´~~igual~~a~~1$

$Logo, ~~para~~igualar~~as~~bases~~1~~sera\´~~igual~~a~~25^0, ~~e~~assim$

$eliminamos~~as~~bases~~e~~resolvemos~~os~~expoentes$




$25^{x+2}=1\to\\\\ 25^{x+2}=25^0\to\\\\ x+2=0\to\\\\ \large\boxed{\boxed{x=-2}}$

Answer 2

Verdades equacoes exponenciais 25(x+2)=1
DEIXAR as BASES IGUAIS

25(×⁺²) = 1        lembrando que : 1 = 25º

(25)(×⁺²) = 25º     BASES iguais

(x + 2) = 0
x + 2 = 0
x = - 2
