Jeśli to:
A. x=1
B. x= 4/3
C. =2
D. x=3/4
Witam ,
Jeśli
log₂2-log₂6=log₂2³-log₂⁶=log₂⁸-log₂⁶= log₂(8/6)=log₂(4/3)
log₂1(3)
Więc odpowiedz B:
x= 4/3
log₂x = 3log₂2 - log₂6 = log₂2³ - log₂6 = log₂8 - log₂6 = log₂(8/6) = log₂(4/3)
log₂x = log₂(4/3)
zatem przy jednakowych podstawach:
x = 4/3
Odp. B. x = 4/3
