Question

qual o valor de :
log3 (72) - log3(12) - log3 (2)?

Answer 1

$log_{3}(72) - log_{3}(12)-log_{3}(2) = log_{3}( \frac{72}{12}) - log_{3}(2) =$

$log_{3}( \frac{72}{12}) - log_{3}(2) = log_{3}(6) - log_{3}(2) = log_{3}( \frac{6}{2}) =$

$\boxed{\boxed{log_{3}( \frac{6}{2}) = log_{3}(3) = 1}}$

Espero ter ajudado. :))
