To find the square root of 144, follow these steps:
1. Start by listing the factors of 144. The factors of 144 are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144.
2. Look for the perfect square factors in the list. A perfect square factor is a number that, when multiplied by itself, gives the original number (in this case, 144). In this case, the perfect square factors are 9 and 16.
3. Take the square root of the perfect square factor. The square root of 9 is 3, and the square root of 16 is 4.
4. Write the square root of the perfect square factor as part of the answer. In this case, the square root of 9 becomes part of the answer, which is √9.
5. Simplify the square root of the perfect square factor. √9 is equal to 3.
6. Multiply the simplified square root by any other remaining factors. In this case, there are no other remaining factors.
7. Write the final answer as a whole number. In this case, the square root of 144 is 12.
Therefore, the correct answer is option c. 12.
Sure, I can help you with that! To find the square root of 144, you need to consider the options provided: 72, -12, 12, and 1/12.
To determine the correct answer, we can calculate the square of each option and see which one equals 144.
Let's start with option (a) 72. If we square 72, we get 5,184, which is not equal to 144, so we can eliminate it.
Next, let's try option (b) -12. Squaring -12 gives us 144, so this is a valid solution.
Now, let's try option (c) 12. Squaring 12 gives us 144, so this is also a valid answer.
Lastly, let's try option (d) 1/12. Squaring 1/12 gives us 1/144, which is not equal to 144. Therefore, we can eliminate this option.
So, the correct answer is either option (b) -12 or option (c) 12.
However, the most common convention when finding square roots is to consider only the positive value. Therefore, the correct answer is option (c) 12.
