The root number three is approximately equal to 1.732. Details are as follows:

1, root sign

The root sign is a symbol used to represent the root operation of a number or an algebra. If a? =b, then a is the n-th root of b or a is the 1/n power of b.

2. Answer process

1.8× 1.8=3.24 (greater than 3).

1.7× 1.7=2.89 (less than and close to 3).

1.74× 1.74=3.02 (greater than 3, it should be discarded).

……

1.73× 1.73=2.9929。

Keep algebra, the closer the number is to 3, the more accurate the result is.

Characteristics of wrong mathematical formula

1, claiming to be scientific, is vague and lacks specific weights and measures.

2. Operation definitions (for example, public variables, ownership or objects that outsiders can also check) cannot be used.

3, can not meet the principle of simplicity, that is, when many variables appear, can not get the answer from the simplest way.

4. Use ambiguous language and a lot of technical terms to make the article look scientific.
