Correct Answer: 4 – 64


Solution : Let's check the options –
First option: 15 – 225→(15) 2 = 225
Second option: 19 – 361→(19) 2 = 361
Third option: 9 – 81→(9) 2 = 81
Fourth option: 4 – 64→(4) 3 = 64

The fourth option is different from the other three options as it represents the cube of the number, not the square. Hence, the fourth option is correct.
