Answer:
If i understood correctly n = 4
Step-by-step explanation:
You are looking for the smallest n that gives a result to the square root so you have to try known squares.
Since you have 60+n, you have to start with 64, 81, 100, etc
First try with 64 means n equals 4
Then you go for the next expresion and replace 4:
2(4) + 28 = 36 which is 6*6
So thats your answer
