If (N=2^6 \times 3^2), by the least number should (N) be multiplied to make it a perfect cube?
Answer and explanation
Correct answer: (3)
Step 1: In a perfect cube, every prime exponent must be a multiple of (3). Step 2: (2^6) is fine, but (3^2) needs one more (3) to become (3^3). Step 3: For cubes, make exponents multiples of (3).
