What is the square root of 49?

• A. 6
• B. 7
• C. 8
• D. 9

Answer: (B)

The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, the number is 49. To determine the square root of 49, we need to think about which number, when squared (multiplied by itself), equals 49. The multiplication process for the number 7 is as follows: 7 × 7 = 49. This confirms that 7 is indeed the square root of 49. Thus, every time we see the square root symbol, we are looking for a number that, when squared, returns us to the original number given, which in this case is straightforward as 7. Other numbers such as 6, 8, and 9 do not yield 49 when squared, as: - 6 × 6 = 36 - 8 × 8 = 64 - 9 × 9 = 81 This reinforces the understanding that the only correct answer to the question about the square root of 49 is 7.
