Scientific Calculator With Square Root

This scientific version of a classic calculator allows you to perform square roots and double-precision calculations more quickly and easily. Check out how the scientific calculator compares to a classic straight calculator. Learn how to calculate weights in kilograms with the scientific calculator.

Root

But square roots are not the only roots you can have. You can also have cube, or third, roots. When calculating the cube root of a number, you're looking for a number that, when multiplied by itself three times, results in the given number. For example, the cube root of 8 is 2 because 2 * 2 * 2 = 8. For the cube root, you'll write a little three in the upper left corner of your root symbol. You can also have fourth, fifth, sixth, or other integer roots, as long as they're a positive real number.

To calculate a square root, you'll use the square root button on your scientific calculator. To use this button, you'll need to know how your calculator operates. Some calculators have you input the number first and then push the square root button. Others have you push the square root button first followed by your number. So to find the square root of 5, for example, you'll push these buttons if your calculator has you input the number first. (Source: study.com)

Number

When using a scientific calculator to find a root, you'll need to follow its manual and see whether you input the number first and then press the root button, or vice versa. The custom root button can be used to calculate cube, fourth, and fifth roots, or any positive integer root. By using the custom exponent button, you can convert the root into a fraction by inverting it. Some calculators also have a caret button (which represents the caret ^ symbol) that you can use in place of your custom exponent button.

= 9. Any nonnegative real number x has a unique nonnegative square root r; this is called the principal square root .......... For example, the principal square root of 9 is sqrt(9) = +3, while the other square root of 9 is -sqrt(9) = -3. In common usage, unless otherwise specified, "the" square root is generally taken to mean the principal square root."[1]. (Source: www.calculatorsoup.com)
