Odpowiedź:
( [tex]log_4 18 - log_4 1,125 )* ( 2 log_3 10 + log_3 0,09 ) =[/tex]
= [tex]( log_4 \frac{18}{1,125} )*( log_3 10^2 + log_30,09 ) =[/tex]
= ([tex]log_4 16 ) * ( log_3 ( 100*0,09 ) = 2 * log_3 9 = 2*2 = 4[/tex]
-----------------------------------------------------------------------
bo [tex]log_4 16 = 2[/tex] gdyż 4² = 16
[tex]log_3 9 = 2[/tex] gdyż 3² = 9
Szczegółowe wyjaśnienie:
" Life is not a problem to be solved but a reality to be experienced! "
