Yes, the square root of 81 is indeed 9.
The square root of a number is a value that, when multiplied by itself, equals the original number. In this case, 9 multiplied by 9 equals 81 (9 * 9 = 81). Therefore, 9 is the square root of 81. Mathematically, this is expressed as √81 = 9.
The prime factorization method can also be used to find the square root of 81. The prime factorization of 81 is 3 x 3 x 3 x 3. This can be rewritten as (3 x 3) x (3 x 3) or 9 x 9. Thus, √81 = √(9 x 9) = 9.
