Question

Questão 05 - Quanto vale M sabendo que M = log4 64 -
log3 81 – log1 – 16.
a) b) c)-3 d)2 e) -4

Answer 1

$log_{4}(64) = log_{ {2}^{2} }( {2}^{6} ) = \frac{6}{2} = 3$

$log(1) = 0$

$log_{3}(81) = log_{3}( {3}^{4} ) = \frac{4}{1} = 4$

$log_{4}(64) - log_{3}(81) - log(1) - 16$

$= 3 - 4 - 0 - 16 = - 17$
