Answer 1

Explicação passo-a-passo:

a)

$\sf{\log_{3}(\frac{81}{27})}$

$\sf{\log_{3}(81÷27)}$

$\sf{\log_{3}(3)}$

$\red{\boxed{\sf{= 1}}}$

b)

$\sf{\log_{4}(1024 \cdot 256)}$

$\sf{\log_{4}(262144)}$

$\sf{\log_{4}(4^9)}$

$\red{\boxed{\sf{= 9}}}$

c)

$\sf{\log_{10}(10^{-2})}$

$\sf{- 2 \cdot (\log_{10}(10))}$

$\sf{- 2 \cdot (1)}$

$\red{\boxed{\sf{= - 2}}}$
