The square root of a number is a value that, when multiplied by itself, gives the original number. The square root symbol is $\sqrt{}$. For example:

• $\sqrt{4} = 2$ because $2 \times 2 = 4$.
• $\sqrt{9} = 3$ because $3 \times 3 = 9$.

If the number is not a perfect square (e.g., 2 or 7), the square root is often expressed as an approximation or in radical form (e.g., $\sqrt{2}$, $\sqrt{7}$).

Would you like me to explain square root properties, solve a specific problem, or delve into its applications? 😊
