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, 49 is the number in question. To find its square root, we look for a number that, when squared (multiplied by itself), equals 49.

Starting with the number 7: when we multiply 7 by itself (7 × 7), we get 49. This means that 7 is the square root of 49. No other whole number multiplied by itself will yield 49, making 7 the only correct answer in this context.

The other options do not satisfy the condition of being the square root. Multiplying 6 by itself gives 36, while 8 squared gives 64, and 9 squared results in 81. None of these products matches 49, reinforcing that 7 is indeed the correct square root.
