Let’s analyze the numbers in the options:\[\] (a) 8 - This is (2^3), which is a power of 2.\[\] (b) 64 - This is (2^6), which is a power of 2.\[\] (c) 125 - This is (5^3), which is a power of 5.\[\] (d) 28 - This number is not a perfect cube or a power of 2 or 5. \[\] Numbers (8) and (64) are powers of (2). \[\] (125) is (5^3), which is a perfect cube. \[\] (28) does not conform to these patterns. \[\] Thus, 28 is different from the others because it is neither a power of 2 nor a standard power sequence like 8, 64, or 125.\[\] \[\] Correct Answer: (d)
