you have to chose one
To subtract 823−−√−23−−√, we have to simplify the square roots first.
√23 is approximately 4.8 because 4.8^2 = 23.
√46 is approximately 6.8 because 6.8^2 = 46.
Thus, the simplified expression becomes:
823−4.8−6.8.
To perform the subtraction, we subtract the values inside the square roots:
823−4.8−6.8 ≈ 812.2−6.8.
Finally, subtracting the values gives us:
812.2−6.8 = 805.4.
thats no one of the awncers u have to chose one of the following:
823−−√
8 start root 23 end root
723−−√
7 start root 23 end root
846−−√
8 start root 46 end root
746−−√
7 start root 46 end root
Apologies for the confusion. The correct answer is:
823−−√ is 8√23

To find the difference in miles run each day, we need to subtract the number of miles run on Tuesday from the number of miles run on Monday.
Let's calculate the expression:
76–√ - 56–√
To simplify the square roots:
√6 is approximately 2.45, as 2.45^2 = 6.
√12 is approximately 3.46, as 3.46^2 = 12.
Substituting the values:
76–2.45 - 56–3.46
Now subtracting the values:
73.55 - 52.54 ≈ 21.01
Therefore, the difference in miles run each day is approximately 21.01 miles.
