Answer:
question 1: it is between 8 and 9. question 2: option B.
Step-by-step explanation:
1. since the closest value that IS a squarable number is 64, the square root of 64 is 8. because 66 is greater than 64, we can estimate that <em><u>the square root of 66 is between 8 and 9. </u></em>
<em><u /></em>
2. to solve this, we can take the square root of the numbers to begin.
the square root of 25 is 5 (because 5x5=25)
the square root of 16 is 4
20 is actually not squarable, so we can estimate that it is a little greater 4.
<em><u>the answer would be √16, √20, 4.85, √25</u></em>
it would be option b.
hope this helps!! :))
