3   3   1/2  3  -2  1/3  1  2  2   2

Explicație pas cu pas:

㏒₂8=log₂ 2³=3log₂ 2=3

log₃ 1/27=log ₃ 3⁻³=-3log₃3=-3

log₅$\sqrt{5}$=1/2log₅5=1/2

log₅125=log₅5³=3log₅5=3

log₂1/4=log₂2⁻²=-2log₂2=-2

log₆$\sqrt[3]6}$=1/3log₆6=1/3

log₆2+log₆3=log₆(2*3)=log₆6=1

log₂28-log₂7=log₂(28/7)=log₂4=log₂2²=2log₂2=2

log₂6+log₂14-log₂21=log₂[(6*14)/21]=log₂4=log₂2²=2log₂2=2

log₅100+log₅2-log₅8=log₅[(100*2)/8]=log₅25=log₅5²=2log₅5=2
