Write the following expression without negative exponents and without parentheses, \[ -2 x^{-1} \] Answer Atempt 1 out of 2

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

4 The solution set of the equation: \( X-1=|-1| \) in \( \mathbb{N} \) is ............ \( \begin{array}{llll}\text { (a) }\{0\} & \text { (b) }\{1\} & \text { (c) }\{2\} & \text { (d) } \varnothing\end{array} \)

Belect the equivalent expression, \[ \frac{x^{-2} \cdot x^{5}}{x^{-3}} \] Answer \( \begin{array}{ll}x & \frac{1}{2}\end{array} \)
