Question: 1 / 400

What is the square root of 25?

4

5

The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, the square root of 25 is the number that satisfies the equation \( x \times x = 25 \).

When you take 5 and multiply it by itself, \( 5 \times 5 = 25 \), confirming that 5 is indeed the square root of 25. This understanding is fundamental in mathematics, particularly in algebra, where the concept of square roots is frequently used in various applications. The other numbers listed do not satisfy this equation; for instance, 4 multiplied by 4 equals 16, 6 multiplied by 6 equals 36, and 7 multiplied by 7 equals 49. Thus, 5 is the correct and only valid answer for the square root of 25.
