Answer:
A) 5 and 6
Explanation:
The easiest but longest way to solve this would be to calculate the squares of every number.
5 squared is 25, and 6 squared is 36.
4 squared is 16, and 5 squared is 25.
7 squared is 49, and 8 squared is 64.
6 squared is 36, and 7 squared is 49.
Since 34 is in between 25 and 36, we can see that A, or 5 and 6, is the correct answer.
Hope this helps!
