When you want to type square root, cube root and fourth root symbols on your documents then the easy way is to use alt code shortcuts. Alt Code Shortcut for Square Root Symbol. Square root or principal square root symbol √ does not have 2 on the root. When A 2= B then A is the square root of B indicated as √B = A. For example, √4 = 2. Cube root is written N ^ 1/3 the Negative power means the fraction 1/ N^p; 10^-2 = 1/ 10^2 the power of a root is the number the root of a power is the number Cube root of -1 is the same as -1^1/3 which is the same as -1^2/6. Cube root of -1 equals -1 but -1^2/6 equals 1. Altough they seem to be the same they give different answers.
How to write cube root:
Well, we just happen to know that 125 = 5 × 5 × 5 if you use 5 three times in a multiplication you will get 125. so the cube root of 125 is 5 The Cube Root Symbol This is the special symbol that means "cube root", it is the "radical" symbol used for square roots with a little three to mean cube root. The n th root of a can be written as a fractional exponent with a raised to the reciprocal of that power. When the n th root of is taken, it’s raised to the 1/ n power. When a power is raised to another power, you multiply the powers together, and so the m otherwise written as m /1 and the 1/ n are multiplied together. To calculate cube root by hand, choose a perfect cube that is as close to the answer as possible, write it down, and subtract your estimate from the original number. For example, you could estimate that the square root of 30 was 3. However, 3 cubed is 27, so you would write down 3 as the first part of your answer with a remainder of 3.

To complete John's thought, there are three distinct cube roots of every non-zero number positive real, negative real, complex, not just of the negative real numbers. And as John points out, some of these roots are complex, so you need to know how the tools you are using behave in order to get the answers you want. Entering Math Expressions in LON-CAPA In general, you will enter math expressions in LON-CAPA like you would on most calculators. Use / for division, for multiplication and ^ for power. Here are some speci c rules that I would
