Convert the mathematical expression (2 + 42) / 2 into a Python expression.

The term $4^2$ represents 4 raised to the power of 2. In Python, the exponentiation operator is **. So, $4^2$ is written as 4**2.

The numerator is $2 + 4^2$. Using the Python exponentiation, this becomes 2 + 4**2. To ensure this entire sum is calculated before division, it should be enclosed in parentheses: (2 + 4**2).

The entire numerator is divided by 2. In Python, the division operator is /. So, the full expression is (2 + 4**2) / 2.

• (2 + exp(4,2)) / 2: exp() is typically used for $e^x$ or requires importing math.pow() or pow(). exp(4,2) is not standard for $4^2$.
• (2 + 4**2) / 2: This correctly uses ** for exponentiation and / for division, with parentheses for the numerator.
• (2 + 4'2) / 2: The ' character is not a valid operator for exponentiation in Python.
• (2 + 4^2) / 2: The ^ operator in Python is the bitwise XOR operator, not exponentiation.

The correct option is the second one.

The correct Python expression is $(2 + 4**2) / 2$.
