What is the square root of 144?

The square root of a number ( n ) is a value that, when multiplied by itself, gives the number ( n ). In this case, we are looking for the square root of 144.

To determine this, we can think about what number multiplied by itself results in 144. If we calculate ( 12 \times 12 ), we find that it indeed equals 144. Therefore, the square root of 144 is 12.

This solution aligns with the properties of square roots, confirming that ( 12^2 = 144 ). Understanding these principles helps to see why 12 is the correct answer. Other choices do not yield the correct product when squared, further reinforcing why they are not suitable answers.
