Question

Log0,5 x = 4
log 1/3 x = -1
log pierwiastek z 5 5 =x
log 10 x = -1
log pierwiastek z 1000 = x
log 2 (log n x ) = -1
log 2 (x+1) - log 2 (x+3) = 3
Prosze o rozwiązanie pilne!!

Answer 1

1. 0,5x=10^4=10000 x=20 000
2. 1/3*x=10^-1=0,1 x=0,3
3. =1/2log55=1/2*1,7403=0,8702
4. 10x=10^-1=0,1 x=0,01
5. =1/2log1000=1/2*3=1,5
6. log2(lognx)=-1 2lognx=10^-1 lognx=0,05 nx=1,122 x=1,122/n
7. log2[x+1]-log2[x+3]=3
log2[x+1]/2[x+3]=3 uproszcz.przez2 pod log xróżne od -3
[x+1]/[x+3]=10^3=1000
x+1=1000x+3000
999x=-2999
x=-2999/999
