The square root of a number is defined as a value that, when multiplied by itself, gives the original number. In this case, the square root of 49 asks us to identify a number that, when squared, equals 49.

Calculating the square root of 49, we can consider that 7 multiplied by itself (7 x 7) results in 49. Consequently, 7 is the correct square root of 49. Understanding this relationship between squaring a number and finding its square root is fundamental in mathematics.

The other options do not hold because none of the other numbers, when squared, will yield 49. For example, 6 squared is 36, 8 squared is 64, and 9 squared is 81, all of which do not equal 49. Thus, the confirmation that 7 is the square root of 49 is validated through both multiplication and the foundational concepts of square roots.
