log(3)(x^2-1)=1
log(0,5)(x+2)+log(0,5)(x+3)=-2log(0,5)(x-1)
Срочно ребята контрольная!!!!пожалуйста!!!!

1) log3(2x+1)=22x+1=92x=8x=4 2)log0.2(x^2 + 4x)=-1x^2 + 4x=2x^2 + 4x - 2=0x1=V6 - 2x2=-(V6 + 2) 3)log^2 5(X) - log5(x) -2 =0(log5(X)-2)(log5(x)+1)=0x1=25x2=1/5 4) log1/3(x^2-5x+7)>0x^2-5x+7>1x^2-5x+6>0(x-6)(x+1)>0x1>6x2>-1
