Question

The set { x : x⁴ = 1 and x ∈ R} is …… X …….set. Here, X refers to

Answer 1

Given,

$\[A = \left\{ {x:{x^4} = 1\,{\rm{and}}\,x \in R} \right\}\].$

Solution,

Understand that here it is given that$\[{x:{x^4} = 1\,{\rm{and}}\,x \in R}\]$,

Therefore,

$\[\begin{array}{l} \Rightarrow {x^4} = 1\\ \Rightarrow x = \pm 1\end{array}\]$

Hence, the values of $\[x\]$is $\[ \pm 1.\]$
