Question

Quizplus · Accepted Answer

169 is a perfect square, equal to 13^2. Therefore, the square roots of 169 are 13 and -13. Option B (15, -15) and Option D (26, -26) are not the correct answers as 169 is not a perfect square of either 15 or 26. Option A (14, -14) is close but not exact, as 14^2 is equal to 196, not 169. The square root of 169 is 13, as 13 multiplied by itself equals 169. Therefore, the answer is choice C, which includes 13 as one of the square roots. The negative square root is not included because square roots are by convention taken to be positive.
