Answer:
8.307
Step-by-step explanation:
69 is not a perfect square, and none of its factors (1, 3, 23, 69) are perfect squares. Therefore, the best one can do in finding the square root of 69 is to use a calculator: √69 = 8.307 to three decimal places.
Note that 8² = 64 and that 9² = 81. Since 69 is between 64 and 81, it follows that the square root of 69 lies between 8 and 9, which agrees with the outcome given above.
