(3^1/2)^x=3²
3^1*x/2 =3² mamy równe podstawy potęgi to możemy przyrównać wykładniki
x/2=2 x=4,czyli log√3 9=4
f)log1/3 81=x
(1/3)^x=3^4
3^-x=3^4
-x=4 x=-4
log1/3 81=-4
g)log1/2 √2=x
(1/2)^x=2^1/2
(2)^-x=2^1/2
-x=1/2 x=-1/2
log1/2 √2=-1/2
log1/5 ∛5=x
(1/5)^x=5^1/3
5^-x=5^1/3
-x=1/3 x=-1/3
log1/5 ∛5=-1/3
