1. Which set of senior high school entrance examination papers did the result of calculating (13) ⅹ 2 come from?
The result of calculating (3) ⅹ 2 comes from the mathematics examination paper of the senior high school entrance examination in Anshun City, Guizhou Province in 2020.

The result of calculation (3)

In addition, it should be noted that there are special forms of power with the same base in the senior high school entrance examination paper: constant base, exponential addition, polynomial expansion: square difference, difference square, sum square, cubic difference, etc. , can evolve through reasoning.

General principles of senior high school entrance examination papers

1, calculation accuracy is good: calculation should be careful to avoid unnecessary loss of points.

2. Understand the exam question well: "I would rather get three points than grab a second's answer."

3, to standardize the expression: in strict accordance with the logical expression of the teacher's usual requirements, to avoid losing step.

4. Synchronize thinking and writing: thinking fast and writing slowly are the faults of some students, which easily lead to overlapping of the previous steps, and the logic of writing the problem-solving process is chaotic, resulting in losing points.

5. It is easy to solve problems, but also be careful, for example, the fractional equation should be tested; One-dimensional quadratic equation should pay attention to the fact that the coefficient of quadratic term is not 0. Attention should be paid to using pencils in drawing questions, and traces of drawing should be kept; Big question of probability, three sentences and so on.
