What is the square root of 144?

  1. 10

  2. 11

  3. 12

  4. 13

The correct answer is: 12

The square root of a number is defined as a value that, when multiplied by itself, gives the original number. In this case, the question asks for the square root of 144. To find this, we consider which number, when multiplied by itself, equals 144. When examining the number 12, we calculate \(12 \times 12\), which indeed equals 144. Therefore, the square root of 144 is 12. Recognizing that 10, 11, and 13 do not fulfill this relationship helps confirm that 12 is the correct answer, as none of these numbers, when squared, equal 144. Thus, the answer is definitively 12.
