Question

8.
O valor de
log33
é:

Answer 1

Explicação passo-a-passo:

8) $\sf log_{3}~3=\red{1}$, pois $\sf log_{a}~a=1$

9) $\sf log_{15}~1=\red{0}$, pois $\sf log_{b}~1=0$

10) $\sf 7^{log_{7}~9}=\red{9}$, pois $\sf b^{log_{b}~a}=a$

11) $\sf log_{\sqrt{3}}~(\sqrt{3})^{-6}=\red{-6}$, pois $\sf log_{a}~a^n=n$
