Rozwiąż zadanie z logarytmem 1 lo.
Dam naj
ok zrobilem, nastepnym razem to wyrazniejsze zdjecia bo nic nie widac
:))
1.
log0,1= -1 bo 10⁻¹=0,1
log₃27=3 bo 3³=27
log√₃9=4 bo√3⁴=9
log₄8= 3/2 bo 4^3/2=√4³=8
a zatem
= -1 + 4 =
3 1,5
=-1 + 4 =
3 3/2
-1 + 4 ·⅔= -⅓+ 8/3 =7/3
3
2.
log₃9=2
log⅓ 9= -2 ⅓)⁻²=9
log√₂4=4 √2⁴=4
log₁₆8=¾ 16^¾=2³=8
= 2· (-2) +3 =
4 4
= -¼
