Here is an expression: 2 + 3ⁱ ( Remember what you do when you replace i with a number) Evaluate the expression when i is 1.

Kamila [148]

Answer:

The value of the expression when i is 1 is equals to 5.

Step-by-step explanation:

We are given the following expression:

$2 + 3^{i}$

Evaluate the expression when i is 1.

We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So

$2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5$

The value of the expression when i is 1 is equals to 5.
