which inequalty statment is true?

a. 8 < �ã78 <9
b. 38< �ã78 <40
c. 77 < �ã78 <79
d. 6.083 < �ã78 <6.085

The key to find the right answer is to calculate (perhaps with a calculator) the value of √78=8.832... approx.

Make your choice based on that and post your answer if necessary.

Note: I assume "�ã" is meant to be square root (sqrt(), or √).
