1. The problem asks us to evaluate the expression $13i$ when $i=2$. 2. The expression is a simple multiplication of the constant 13 by the variable $i$. 3. Substitute $i=2$ into the expression: $$13i = 13 \times 2$$ 4. Multiply 13 by 2: $$13 \times 2 = 26$$ 5. Therefore, the value of the expression $13i$ when $i=2$ is $26$.
