What is the square root of 49?

• A. 6
• B. 8
• C. 7
• D. 9

Answer: (C)

The square root of 49 is the number that, when multiplied by itself, gives the product of 49. In this case, 7 multiplied by 7 equals 49, making 7 the correct answer. The relationship of squaring and square roots is fundamental in mathematics, where the square root is essentially the inverse operation of squaring a number. Therefore, since \(7^2 = 49\), it follows that the square root of 49 must be 7. This concept is critical in problem-solving and can be applied in various mathematical contexts, including simplifying expressions and solving equations.
