fortran90 is the symbol for opening the square root

Exponential functions can be used, e.g. to the third power of x can be expressed as x**(

Fortran was taught in college more than 20 years ago, and I can't remember exactly. However, many languages are the same, the sqrt function is actually a special case of the exponential function, because it is used more, so there will be special functions, 3rd power root, 4th power root, etc., there may not necessarily be a separate function, but you can directly apply the exponential function to evaluate.

x (1 3), x is the number.

For example, the cube root of 1000.

Write 1000 (1 3).

As early as the first century B.C., China's classic mathematical work "Nine Chapters of Arithmetic" was published, which introduced the above-mentioned method of pen arithmetic for the first time in the history of mathematics in the world. According to historical records, it was not until the fifth century A.D. that the Kaiping method was introduced abroad. This shows that in ancient times, China was far ahead in the world in the study of prescriptions.

Steps of opening a square pen calculation method:

1 divides the integer part of the open square number into groups every three digits from the single digit to the left;

2 According to the leftmost group, find the highest digit of the cube root;

3 Subtract the cube with the highest digit of the cube root from the first set of numbers, and write the second set of numbers to the right of it;

4. Use 300 times the square of the highest digit obtained to divide the above remainder to obtain the test quotient; And the 300 times of the square of the highest digit obtained and the product of the test quotient, the 30 times of the highest digit obtained and the product of the square of the test quotient and the cube of the test quotient are written on the left side of the vertical type, observe whether the sum is greater than the remainder, if it is greater, reduce the test quotient and try again, if it is not greater, the test quotient is the second digit of the cube root;

5 Continue in the same way.

Property (1) Within the range of real numbers, there is only one cubic root of any real number (2) Within the range of real numbers, negative numbers cannot be squared, but they can be squared.

3) The cube root of 0 is 0

4) The cubic and open square operations are inverse operations of each other.

5) In the range of complex numbers, any non-0 number has only 3 cubic roots (one real root, two conjugate imaginary roots), which are evenly distributed on the circumference of the circle with the origin as the center and the arithmetic root as the radius, and the points corresponding to the three cubic roots form a regular triangle.

2) In the range of complex numbers, negative numbers can be both square and squared.

Hope it helps, the right answer.

For example, if the cube of a number is equal to a, then this number is called the cube root of a, also known as the cubic root, that is, if x = a, then x is called the cube root of a.
