What is the square root of 8?

The correct answer is: 4

When we take the square root of a number, we are asking ourselves "what number multiplied by itself equals the given number?" In the case of 8, the square root is 4 because 4 multiplied by itself (4 x 4) equals 8. This means that options A, B, and D are incorrect because they do not equal 8 when multiplied by themselves. While it may seem like 8 is closer to 5 or 6, the fact that they cannot be squared to equal 8 makes them incorrect answers. Option C, 4, is the only choice that satisfies the requirement of being multiplied by itself to equal 8, making it the correct answer.
