If (N=2^4\times3^5\times5^2), by which smallest number must (N) be multiplied to make it a perfect cube?
Answer and explanation
Correct answer: (2^2\times3\times5)
Step 1: For a perfect cube, every exponent must be a multiple of 3. Step 2: To make powers (4,5,2) into (6,6,3), we need (2^2), (3), and (5). Step 3: So the smallest multiplier is (2^2\times3\times5).
