Exponentiation has higher precedence than multiplication and division, so evaluate 16 ** 2 before performing the division.

1) Relevant concepts:
- Operator precedence: exponentiation (**) binds tighter than multiplication/division (*, /).
- Associativity: multiplication and division are left-to-right when at the same precedence level.
- In many languages (e.g., Python), / produces a floating-point result, but the numeric value remains the same (64.0 equals 64).

2) Step-by-step reasoning and intermediate calculations:
Step 1 — compute the exponent:
16 ** 2 = 16 × 16 = 256

Step 2 — perform the division:
256 / 4 = 64

So the expression is evaluated as (16 ** 2) / 4 = 256 / 4 = 64.

3) Why this is correct:
Because ** is evaluated before / according to standard operator precedence rules, you must compute 16 squared first. Only after that do you divide the resulting 256 by 4.

4) Why common incorrect results are wrong:
- Getting 4 would come from incorrectly evaluating 2 / 4 first (2/4 = 0.5) then computing 16 ** 0.5 = 4. That ignores operator precedence.
- Getting 256 would mean forgetting to divide by 4 after computing the exponent.
- In Python 3 the result of 256 / 4 is 64.0 (a float), but its numeric value matches 64; if an integer is required one could use integer division (//) to get 64.

Conclusion: Following operator precedence and the shown arithmetic yields 64, which matches the provided answer.
