Because 13 and -13 multiplied together both = 169:
There are two because the square root of 16 for example is 4 or -4
-9 and 5 are two possible answers.
√144 < √165 < √169 12 < √165 < 13
Do you mean: What is the square root of (8 squared)? If so, there are two answers: 8 and -8. Or do you mean: What is the (square root of 8) squared? If so, there is only one answer: 8.
8
There are two answers: 20 and -20
There are two roots, both real: -13 and +13
The square root of 150 is between 12 and 13.
There are two because the square root of 16 for example is 4 or -4
The two square roots of the number, '169', are +13 and -13 .
-9 and 5 are two possible answers.
There are two possible answers because if you square a negative number, you will get a positive answer.
√144 < √165 < √169 12 < √165 < 13
Do you mean: What is the square root of (8 squared)? If so, there are two answers: 8 and -8. Or do you mean: What is the (square root of 8) squared? If so, there is only one answer: 8.

169 = 13 X 13
There are two answers to that: 1² + 13² = 1 + 169 = 170 7² + 11² = 49 + 121 = 170
