The equation “square root of (4 plus the square root of x) equals 5” has been circulating online as a “Harvard entry question,” intriguing many with its layered structure.
While it may appear complex at first, the solution is straightforward when broken down step by step.
Since the square root equals 5, the expression inside the square root must equal 25. This simplifies to:
4 plus the square root of x equals 25.
Next, subtract 4 from 25, leaving the square root of x equal to 21.
The final step is to square both sides, resulting in x equal to 441.
What makes this question captivating is its ability to challenge problem-solving skills without requiring advanced math knowledge. The beauty lies in simplifying what initially feels overwhelming.
The answer, x = 441, highlights the importance of approaching problems systematically.
So, the next time you encounter a brain teaser like this, remember that patience and logical thinking are your best tools. It’s not just about finding the answer—it’s about enjoying the process of discovery.
