Mathematics has accompanied the great transformations of our history long before the advent of calculators and computers. It has enabled astronomers to understand the movement of celestial bodies, architects to envision increasingly ambitious structures, and scientists to translate natural phenomena into numbers and equations. What I enjoy about small mathematical challenges is that they remind us of a very simple truth: an impressive calculation is not necessarily a difficult one.
I remember hesitating for a long time in front of an equation containing a square root, simply because the symbol seemed complicated to me. Once the square root was calculated, everything else became almost immediate. This is often the case in mathematics: one must progress step by step.

What Your Performance Can Reveal
If you found the result quickly and correctly, you have excellent logic and analytical skills.
If you found the result after some thought, you know how to structure your reasoning and check your steps.
And if your result was incorrect or not found, don’t worry; this type of exercise is perfect for improving method and precision.
Detailed Solution We Found (Not Necessarily the Only One, or Even the Correct One)
Let’s start with the power:
4² = 4 × 4 = 16
Next, we calculate the square root:
√16 = 4
The equation then becomes:
(16 + 4) ÷ 4
We perform the addition in the numerator:
16 + 4 = 20
We are left with:
20 ÷ 4 = 5
Final Answer
5
Conclusion
This challenge shows that an equation containing a power, a square root, and a fraction can become quite simple when we respect the order of calculations. The main difficulty was not performing large operations but knowing where to start.
It’s an excellent habit to develop in mathematics: instead of trying to calculate everything at once, break the problem down into small steps. Here, a few simple calculations were enough to arrive at the correct answer: 5.
