Answer

Answer:

$\varnothing$

Explanation:

Step1: Recall intersection definition

The intersection $Q\cap R$ is the set of elements that are in both $Q$ and $R$.

Step2: Check elements in sets

Elements of $Q={- 2,-1,1,2}$ and $R ={-5,-3,0,3,5}$. There are no common elements. So $Q\cap R=\varnothing$.
