By saying SQRT(50) = (2) X SQRT(25) is wrong because
(2) X SQRT(25) = SQRT(4) X SQRT(25) = SQRT (100)
B -
To estimate the square room of 50, we have to break 50 into multiples like 1 X 50, 2X25 The ideal multiple should consist at least one integer that can be square root into an integer. Now, let’s start with the multiples of 50.
1 X 50, 2 X 25, 5 X 10,
The most deal multiple is 2 X 25 as it contains an integer 25, that can be squareroot into another integer. Hence, it will be SQRT(2) X SQRT(25) = SQRT (2) X 5 = (1.41) X 5 = 7.05
The answer is that Jade's chickens laid more eggs. Since Jade's farm includes 9 chickens, which each laid 3 eggs, multiply 9 and 3 and you get 27. Edna's farm has chickens which, in total, laid 23 eggs, leading to Jade's chickens with 27 eggs to be more than the eggs laid by Edna's chickens. :)
