Are the following relations $R_1$ and $R_2$ defined on the set $\mathbb{Z}$ of integers partial orders? (A partial order is reflexive, antisymmetric and transitive.)$a$ $R_1$ $b$ if and only if $a = 2b$. $a$ $R_2$ $b$ if and only if $a^2|b$.Would someone help me understand?
Are these two relations on integers partial orders?
