\[\frac{8^{x+1}-40}{2 \cdot 64^x-32} \leq 1 .\]
\[\frac{4}{3^x-27} \geq \frac{1}{3^x-9} .\]
\[\frac{\log _3(9 x) \cdot \log _4(64 x)}{5 x^2-|x|} \leq 0 .\]
\[\log _{16}(x+5)+\log _{x^2+10 x+25} 2 \geq \frac{3}{4} .\]
\[\log _{0,5}\left(x^3-3 x^2-9 x+27\right) \leq \log _{0,25}(x-3)^4 .\]
\[\log _4\left((x-5)\left(x^2-2 x-15\right)\right)+1 \geq 0,5 \cdot \log _2(x-5)^2 .\]
