log0,75 1 i 7/9 ...... , log1,5 8/27 ........... , log0,1 1000 .. Bradzo proszę o rozwiązanie dam naj :)
log0,75 1 7/9 =x
log3/4 16/9 =x
3/4^x=16/9
3/4^x=(4/3)^2
3/4^x=(3/4)^-2
x=-2
log1,5 8/27=x
3/2^x = 8/27
3/2^x= (2/3)^3
3/2^x=(3/2)^-3
x=-3
log1/10 1000= x
1/10^x = 1000
10^-x =10^3
-x = 3 /:(-1)
x = -3
