Mathematical radical sign is a basic mathematical operation, which can be calculated by many methods, including Newton method, dichotomy, direct calculation and so on. Among them, one of the most commonly used methods is Newton method.

1, Newton method

Newton method is an iterative algorithm for finding the roots of functions. Based on Newton's theorem, we iterate from the initial estimation until we find a solution that meets the accuracy requirements. For the open root problem, we can turn the problem into the root of the solution function. Where a is the root sign.

Step 2 Use a calculator or software

Now there are many calculators or softwares that can calculate the root number conveniently. For example, calculator software or Excel software can be used on the computer. When using these tools, you only need to input the root number and the required precision to get the value of the root number.

Expand knowledge:

Mathematics, English: Mathematics, from ancient Greece? θημα; Often abbreviated as math or maths, it is a discipline that studies concepts such as quantity, structure, change, space and information. Mathematics is a general means for human beings to strictly describe and deduce abstract structures and patterns of things, and can be applied to any problems in the real world.

All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.

Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology. In ancient China, mathematics was called arithmetic, also called arithmetic, and finally it was changed to mathematics. Arithmetic in ancient China was one of the six arts.

Mathematics originated from the early production activities of human beings, and the ancient Babylonians had accumulated some mathematical knowledge, which could be applied to practical problems. As far as mathematics itself is concerned, their mathematical knowledge is only obtained through observation and experience, and there is no comprehensive conclusion and proof, but their contribution to mathematics should also be fully affirmed.
