Question

If 16 – 2 = 2, 9 – 3 = 0, 81 – 1 = 8, then what is 64 – 4 = ?

• A. 4
• B. 2
• C. 6
• D. 8

Hint:

Check if the numbers relate to square roots or other basic operations to identify hidden patterns.

Answer 1

The Correct Option is A

Let’s analyze the pattern in the given expressions:
- For 16 – 2 = 2: Note that the square root of 16 is 4, and 4 – 2 = 2.
- For 9 – 3 = 0: Square root of 9 is 3, 3 – 3 = 0.
- For 81 – 1 = 8: Square root of 81 is 9, and 9 – 1 = 8.
Following the same logic for 64 – 4:
Square root of 64 is 8,
8 – 4 = 4.
Therefore, the answer is 4.
