Answer: A is equal to 8
Explanation:
sq rt of 77 is between sqrt of 81 and 64, which are 9 and 8. (9 times 9 is 81, 8 times 8 is 64.)
meaning it would be 8.somethingsomethingsomething
interger 8 is less than 8.somethingsomethingsomething, and plus 1 is 9 which more more than 8/somethingsomethingsomething.
ANSWER IS 8
