Every two bits from the cell to the left are a segment. If there is a decimal, every two digits from the right of the decimal point are used to separate the parts. Find the complete square number not greater than the first number on the left, which is "quotient";

Subtract the quotient from the first part on the left and write their difference in the second part on the right as the first remainder; Multiply the quotient by 20 and try to divide it by the first remainder to get the largest integer as the trial quotient (if this largest integer is greater than or equal to 10, use 9 or 8 as the trial quotient);

48= 16×3, radical number: 4 and radical number 1/3 or written as (4 and radical number 3)/3. How many groups of squares do you need to remember to open a quadratic power in mathematics, such as 3? =9,4? = 16, 5? =25 6? =36, 7? =49, 8? =64 9? =8 1 and then split it according to the number given by the title. For example, topic 48 can be divided into 4? ×3。

Extended data:

The n-th root of the number A (n is a natural number) refers to the number whose power n is equal to A, that is, the number B whose power n is equal to A. For example, the fourth root of 16 has 2 and -2. The square root of a number is called the square root; A cube root is called a cube root. All quadratic roots are collectively called square roots. The operation of finding the square root of a given number is called square root. How many square roots a number has is related to both the range of the number and the number of square roots.
