(log_{10}(1))/(2x)>0

解答

\frac{lo g _{10} ( 1 )}{2 x} > 0

无解

求解步骤

\frac{lo g _{10} ( 1 )}{2 x} > 0

乘开

\frac{lo g _{10} ( 1 )}{2 x} : 0

0 > 0

x \in R 无解

\frac{( 15 - 4 x )}{( x ^{2} - x - 12 )} < 4

\frac{( x + 7 )}{x} > 5

\frac{4}{x + 3} > 5

\frac{( 2 x - 5 )}{( x - 11 )} \leq 0

x^{2} + 6 > 0
