Correct answer only ! simplify the radical and match to the correct answer choice.

1. √169 = √(13 · 13)  = 13

2. √169 = √(13 · 13)  = 13

3. √81 = √(9 · 9)  = 9

4. √225 = √(15 · 15)  = 15

5. √196 = √(14 · 14)  = 14

4, 3, 1, 5, 2

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
