What is the calculator button for square roots?

The calculator button for square roots is usually labelled as "√" or "sqrt".

On most scientific calculators, the square root function is represented by the symbol "√". This button allows you to find the square root of a number, which is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16.

To use the square root function, you typically press the "√" button followed by the number you want to find the square root of. For instance, to find the square root of 25, you would press "√" and then "25". Some calculators might require you to enter the number first and then press the "√" button. Always check your calculator's manual if you're unsure.

In addition to the "√" button, some calculators might use "sqrt" to denote the square root function. This is more common in software-based calculators or graphing calculators. Regardless of the label, the function remains the same.

Understanding how to use the square root button is essential for solving various mathematical problems, especially those involving quadratic equations and geometry. Practising with your calculator will help you become more comfortable and efficient in using this function.
