Final answer:
The ones digit of the square root of 5329 is 3, since squaring 3 ends with a 9, which matches the ones digit of 5329.
Step-by-step explanation:
The possible ones digit of the square root of 5329 can be determined by looking at the ones digit of the number itself. When you take the square root of a number, the resulting ones digit must correspond to a number which when squared ends in the same digit as the original number. For instance, if you square numbers that end in 1, 4, 9, 6, and 5, the resulting square numbers will end in 1, 6, 1, 6, and 5, respectively. Therefore, since 5329 ends with a 9, the square root could end with a 3 or a 7, as squaring either 3 or 7 will give you a number ending in 9. Therefore, the correct ones digit of the square root of 5329 is 3.
