Question

se ㏒3 1/27=x, então o valor de x é?

Answer 1

3^x = 1/3³

3^x = 3^(-3)

x = -3

Answer 2

$Log_aB=c \Longleftrightarrow a^c= B \\ \\ Log_3 \frac{1}{27}= x \Longleftrightarrow 3^x= \frac{1}{27} \\ \\ Log_3 \frac{1}{27}= x \Longleftrightarrow 3^x= \frac{1}{3^3}\\ \\ Log_3 \frac{1}{27}= x \Longleftrightarrow 3^x= 3^{-3}\\ \\ Log_3 \frac{1}{27}= x \Longleftrightarrow \boxed{ x={-3}}$


Até outra vez!!!!
