for a cube root symbol hold down the ALT button and type 0179 and a little symbol should appear looking like ³ this it's actually the cubed root symbol, not an s!
The radical symbol √ (with a line over what you're taking a root of) denotes root.The symbol without any other numbers, means square root, while with a number like 3√ means take cube root, 4√ fourth root, etc.If you want to type this symbol in Windows, hold down the key on the keyboard, then type (on the number pad) 251, then let go of the key.You can also denote roots by fractional exponents: 1/2 power is the square root,1/3 power is the cube root, etc and this works if you have an xy (exponentiation)key on your calculator and want to compute roots.The symbol used to make a root is √
To type the square root symbol on ypur keyboard press and hold alt and type 251.
It means it is a different kind of root, such as a cubic root, which has a three above the square root symbol ('radical sign'). If y is the square root of x, it means that y2 = x. So the square root of 4 is 2, and 22 is 4. If y is the cube root of x, it means that y3 = x. So the cube root of 8 is 2, and 23 = 8.
2 cube root 24 plus 3 cube root 81 is 18.7492444
