(log_{10}(1))/(2(5-2x))<0

解答

\frac{lo g _{10} ( 1 )}{2 ( 5 - 2 x )} < 0

无解

求解步骤

\frac{lo g _{10} ( 1 )}{2 ( 5 - 2 x )} < 0

乘开

\frac{lo g _{10} ( 1 )}{2 ( 5 - 2 x )} : 0

0 < 0

x \in R 无解

x (x^{2} - 4) \leq 0

\frac{( 2 x + 5 )}{( x + 7 )} > 3

(x + 10)^{2} < 1

\frac{( ( x ^{2} - 81 ) ( x - 9 ) )}{( ( x - 1 ) ( x - 6 ) )} \geq 0

(x + 1) (3 x - 1) > 0
