Answer

$2 \overrightarrow{ i}$

Work Step by Step

We can see that the notation $\lt a, b \gt $ is same as that of $a \overrightarrow{i} +b \overrightarrow{ j}$ We have: $ a= 2 $ and $b =0$ Thus, our answer becomes: $a \overrightarrow{i} +b \overrightarrow{ j} =2 \overrightarrow{i} +(0) \overrightarrow{ j}= 2 \overrightarrow{i} +0 \overrightarrow{ j} = 2 \overrightarrow{ i}$
