Question

Queria saber como é o desenvolvimento:

Log4 (x+4) = 3

Answer 1

$\displaystyle\mathsf{\log_4{(x \: + \: 4)} = 3}\\\displaystyle\mathsf{{x \: + \: 4} = 4^3}\\\displaystyle\mathsf{{x \: + \: 4} = 4^3}\\\displaystyle\mathsf{{x \: + \: 4} = 64}\\\displaystyle\mathsf{x = 64 \: - \: 4}\\\displaystyle\mathsf{x = 60}$

Resposta: x = 60
