Question

sa se calculeze log  x  ia pe rand valorile 8, 1 , √1 /2 , ∛64

Answer 1

$1)log _{x}8= log _{x}2^3=3log _{x}2.$
$2)log_{x}1=0$
$3)log_x \sqrt{ \frac{1}{2} }= \frac{1}{2}log_x \frac{1}{2}=- \frac{1}{2}log_x2$
$4)log_x \sqrt[3]{64}=log_x \sqrt[3]{4^3} =log_x4=2log_x2$
 atat poti sa faci in baza x.
