1) \( (x-6)(3-17 x)(2 x+8) \leq 0 \) 2) \( \left(x^{2}+5 x-6\right)(7 x-11)>0 \) 3) \( (3+5 x)\left(2 x^{2}-6 x+4\right)<0 \)

5 If \( -1<x<3, x \in \mathbb{R} \), then \( (x+1) \in \ldots \ldots \ldots \ldots \) \( \begin{array}{lll}\text { (a) }\{0,3\} & \text { (b) }[-1,3[ & \text { (c) }\{0,4\}\end{array} \)

Simplify: \[ \left(x^{5}\right)^{4} \]
