Simplest quadratic root calculator
The main method to determine whether a quadratic radical is the simplest quadratic radical is to follow the definition of the simplest quadratic radical, or to visually observe that the exponent of each factor (or factor) of the radicand is less than the root exponent 2, and the radicand does not contain a denominator. When the radicand is a polynomial, it must be factored before observation.
Example: Which of √8, √18, √32, √2, 3√3, and 5√5 are the simplest quadratic radicals?
Answer: √2, 3√3, and 5√5 are the simplest quadratic radicals.
From the above examples, it can be seen that when encountering a quadratic radical, simplifying it will make it easier to solve the problem.
A quadratic radical that satisfies the following two conditions is called the simplest quadratic radical:
(1) The factors of the radicand are integers and the factors are integers;
(2) The radicand does not contain any factors or factors that can be completely squared.
