Answer:
The factors of 7 are 1, and 7.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
The factors of 27 are 1, 3, 9, and 27.
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.
Step-by-step explanation: I hope this helps :).
I would say (I am abbreviating square root to sqrt)
1. 4 sqrt(8488) = 4 sqrt(2x2x2122) = 8 sqrt(2122)
2. 3 sqrt(6936) = 3 sqrt(6x34x34) = 102 sqrt (6)
3. 2 sqrt(8648) = 2 sqrt(2x2x2162) = 4 sqrt(2162)
option B is correct. Once have a look to this solution that I have answered
