二次根式的运算可以类比于有理数的运算，有理式运算的算律（结合律、分配律等）仍适用于二次根式的运算．把单个根式类比单项式，把多个根式的代数和类比多项式，则二次根式的除法可类比于整式的除法运算．我们通常把被除式看成分子，把除式看成分母，则二次根式的除法运算可 The quadratic roots operation can be analogous to the rational number operation, and the rationality operation’s arithmetic (combination law, distributive law, etc.) is still applicable to the quadratic root operation. For a single root analogy of monomials and multiple roots of algebra and analog polynomials, the division of quadratic roots can be analogized to the division of integers. We usually look at the divisor as a component and the divisor as a parent, and then the second-order division can be
