If the root index is the same, you can multiply the parts in the root symbol, and the root index remains unchanged. For example, the root number 2 times the root number 3 to get the square root of 6.

Square root is a mathematical operation, which refers to the operation of finding the square root of a number and is the inverse operation of a power.

The number 4 is 2 after the square root and 2 is the result of its square root. This number that represents a number with two identical numbers is called square root 4=2x29=3x32, and 3 is the number after the square roots of 4 and 9.

On the formula of any power of any number: let the root number be a, the root number be b, and c be a variable.

For the first time, the value of c is 1, bringing in the calculation results of constants A and B, replacing the variable C in the formula with the calculation results, and then replacing the calculation results again. When C= the calculation result of the formula, c is the root cycle step, which is affected by the length of the root sign. This method can also be done by writing. I have studied it myself, and the method is absolutely correct! AB can be decimal, fractional or negative. This method is a successive approximation method. Programming can be implemented simply.
