Question

Determine o valor de x em cada equação logaritmo abaixo:
A) Log64 4=x
B)Logx 8=3
C)Log8 4=x

Answer 1

Resposta:

Explicação passo-a-passo:

$a) \\log64(4)=x \\log64 (\sqrt[3]{64})=x \\ log64(64^{\frac{1}{3} })=x\\\\\frac{1}{3}.log64(64) = x\\\\\\x=\frac{1}{3} \\\\b)\\\\logx(8)=3\\x^{3}=8\\ x=2\\\\c)\\\\log8(4)=x \\\\ x= 1 - log8(2)$
