Calcule o valor dos logaritmo
[tex] log\frac{1}{4} \sqrt[2]{2} [/tex]
​

Resposta :

[tex]log(10) ( \frac{1}{4} ) \times \sqrt{2} \\ \\ log(10) ( {2}^{ - 2}) \times \sqrt{2} \\ \\ - 2 log(10) (2) \times \sqrt{2} \\ \\ s = - 2 log(10) (2) \times \sqrt{2} [/tex]

Resposta:

[tex]\log_{1\over4}\sqrt{2} =x\\ \\ ({1\over4})^x=\sqrt{2} \\ \\ ({1\over2^2})^x=2^{1\over2}\\ \\ 2^{-2x}=2^{1\over2}\\ \\ -2x={1\over2}\\ \\ -4x=1\\ \\ 4x=-1\\ \\ x=-\dfrac{1}{4}[/tex]
