Question

Log0,1(1-3x) больше -1

Answer 1

-1 \\ ODZ:x< \frac{1}{3} \\ log_{0,1}(1-3x)>log_{0,1}0,1^{-1} \\ 0<0,1<1 \\ 1-3x<10 \\ -3x<9 \\ x>-3 \\ x~prinadlejit~(-3; \frac{1}{3})- otvet" alt="log_{0,1}(1-3x)>-1 \\ ODZ:x< \frac{1}{3} \\ log_{0,1}(1-3x)>log_{0,1}0,1^{-1} \\ 0<0,1<1 \\ 1-3x<10 \\ -3x<9 \\ x>-3 \\ x~prinadlejit~(-3; \frac{1}{3})- otvet" align="absmiddle" class="latex-formula">
