Answer:
A. {2.82, √8, √11, 3 1/2}
Explanation:
A. {2.82, 2.83, 3.32, 3.5}
√8 = 2.82842712475 or 2.83 when rounded to the nearest hundredth.
√11 = 3.31662479036 or 3.32 when rounded to the nearest hundredth.
To find the square root you multiply a factor of a number by itself in order to get that number.
3 1/2, or 7/2 = 3.5
To convert a fraction into a decimal you divide the numerator by denominator.
B. {2.24, -2.45, 2.5, -3}
√5 = 2.2360679775 or 2.24 when rounded to the nearest hundredth.
-√6 = -2.44948974278 or -2.45 when rounded to the nearest hundredth.
2 1/2, or 5/2 = 2.5
C. {-4, -4.12, -4.24, -4.36}
-√16 = -4
-√17 = -4.12310562562 or -4.12 when rounded to the nearest hundredth.
-√18 = -4.24264068712 or -4.24 when rounded to the nearest hundredth.
-√19 = -4.35889894354 or -4.36 when rounded to the nearest hundredth.
D. {3.16, 4, 2, 1.5}
√10 = 3.16227766017 or 3.16 when rounded to the nearest hundredth
√4 = 2
