1. The square roots of the given numbers are:
A. square root of 0.12 ≈ 0.346
B. square root of 0.1257486 ≈ 0.354
C. square root of 0.12121212 ≈ 0.348
D. square root of 0.111111 ≈ 0.333
2. The square roots of the given numbers are:
A. square root of 121 = 11
B. square root of 150 ≈ 12.247
C. square root of 400 = 20
D. square root of 1,000,000 = 1000
3. The perfect square number is:
A. 32 is not a perfect square.
B. 144 is a perfect square since it is equal to 12^2.
C. 1,000 is not a perfect square.
D. 36,000 is not a perfect square.
4. The dimensions of the bedroom are:
A. Each side of the bedroom as a length of 25 feet.
B. Each side of the bedroom as a length of 156.25 feet.
C. Each side of the bedroom as a length of 390,625 feet.
D. Each side of the bedroom as a length of 312.5 feet.
5. The estimated value of the square root of 50 is:
A. between 5 and 6
B. between 6 and 7

1. To find the square root of a number, you can use a calculator or a mathematical method. In this case, we have four options: A, B, C, and D. To determine the square root, we can input each option into a calculator and find the square root value.
2. Similarly to question 1, we will find the square roots of the given numbers by using a calculator or the mathematical method.
3. A perfect square is a number that can be expressed as the square of an integer. To determine which number is a perfect square, we can find the square root of each option using a calculator or mathematical method. If the square root is an integer, then the number is a perfect square.
4. The area of a square is calculated by multiplying the lengths of both sides. In this case, the area is 625 square feet. To find the dimensions of the bedroom, we need to find the square root of 625. By taking the square root, we can determine the length of one side, which will be the same for all sides of a square.
5. To estimate the value of the square root of 50, we need to consider the approximate values of the square roots of nearby numbers. In this case, we can consider the square roots of 49 and 64, which are 7 and 8 respectively. Since 50 is between 49 and 64, its square root will be between 7 and 8.
What are your attempts?
by the way 25 * 25 = 625 !!!!
