What are the Square Root(s) of 256? Select All That Apply

In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. In this article, we will explore the square roots of 256 and determine which of the given options are correct.

A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16. The square root of a number can be positive or negative, and both values are considered square roots of the number.

To find the square root of 256, we need to determine which numbers, when multiplied by themselves, give 256. We can start by listing the perfect squares that are less than or equal to 256.

1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
5^2 = 25
6^2 = 36
7^2 = 49
8^2 = 64
9^2 = 81
10^2 = 100
11^2 = 121
12^2 = 144
13^2 = 169
14^2 = 196
15^2 = 225
16^2 = 256

As we can see, 16^2 equals 256, so the square root of 256 is 16.

In addition to the positive square root of 256, we also need to consider the negative square root. Since the square of a negative number is the same as the square of its positive counterpart, the negative square root of 256 is also 16.

Now that we have determined the square root of 256, let's examine the other options provided.

A. -128: This is not a square root of 256, as (-128)^2 equals 16384, which is not equal to 256.
B. -16: This is not a square root of 256, as (-16)^2 equals 256, but we have already determined that the square root of 256 is 16, not -16.
C. -12: This is not a square root of 256, as (-12)^2 equals 144, which is not equal to 256.
D. 12: This is not a square root of 256, as 12^2 equals 144, which is not equal to 256.
E. 14: This is not a square root of 256, as 14^2 equals 196, which is not equal to 256.
F. 16: This is a square root of 256, as we have already determined.
G. 128: This is not a square root of 256, as 128^2 equals 16384, which is not equal to 256.

In conclusion, the square root of 256 is 16, and the negative square root of 256 is also 16. Therefore, the correct answer is F. 16.

The final answer is F. 16.
Frequently Asked Questions About Square Roots of 256

In our previous article, we explored the square roots of 256 and determined that the correct answer is F. 16. However, we understand that there may be additional questions and concerns about this topic. In this article, we will address some of the most frequently asked questions about the square roots of 256.

A: A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16.

A: There are two square roots of 256 because the square of a negative number is the same as the square of its positive counterpart. In other words, (-16)^2 equals 256, just like 16^2 equals 256.

A: -128 is not a square root of 256 because (-128)^2 equals 16384, which is not equal to 256. The square of -128 is a much larger number than 256.

A: 12 is not a square root of 256 because 12^2 equals 144, which is not equal to 256. The square of 12 is a much smaller number than 256.

A: Here are a few more examples of square roots:

The square root of 9 is 3, because 3 multiplied by 3 equals 9.
The square root of 25 is 5, because 5 multiplied by 5 equals 25.
The square root of 36 is 6, because 6 multiplied by 6 equals 36.

A: To find the square root of a number, you can use a calculator or a mathematical formula. One way to find the square root of a number is to look for a perfect square that is less than or equal to the number. For example, to find the square root of 256, you can look for a perfect square that is less than or equal to 256. In this case, the perfect square is 16^2, which equals 256.

A: A square root and a square are related but distinct concepts. A square root is a value that, when multiplied by itself, gives the original number. A square, on the other hand, is the result of multiplying a number by itself. For example, the square root of 16 is 4, but the square of 4 is 16.

In conclusion, we hope that this article has provided helpful answers to some of the most frequently asked questions about the square roots of 256. If you have any further questions or concerns, please don't hesitate to ask.

The final answer is F. 16.
