Question

para que valores de x temos log 1/2 ^(x+2)^2=log 1/2^36​

Answer 1

Resposta:

x = -8 ou x = 4

Explicação passo-a-passo:

CE: (x + 2)² > 0

x ≠ -2

logb = logc ⇔ b = c

$log_{\frac{1}{2}}(x+2)^{2}=log_{\frac{1}{2}}36\\\\(x+2)^{2}=36\\\\x+2=-6\\\\x=-6-2\\\\x=-8\\ou\\x+2=6\\\\x=6-2\\\\x=4$
