PCEP Practice Question: Data Types, Variables, Basic I/O and Operators

A developer writes: total = 2 ** 3 + 4. What is the value of total?

⚠ Common exam trap

Python Institute often tests operator precedence by combining exponentiation with addition, trapping candidates who mistakenly evaluate left-to-right or confuse ** with multiplication.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

12

In Python, the exponentiation operator (**) has higher precedence than addition (+). Therefore, 2 ** 3 is evaluated first, yielding 8. Then 8 + 4 equals 12. Option B is correct.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • 16

    Why it's wrong here

    This would be 2**4 = 16, but the expression is 2**3+4.

  • 12

    Why this is correct

    Correct: 2**3 = 8, 8+4 = 12.

  • 14

    Why it's wrong here

    No clear calculation results in 14.

  • 10

    Why it's wrong here

    This would be 2**(3+4) = 128, not correct.
