1. First, enter "Word 20 16" in the search box in the lower left corner of Windows, and then double-click the left key to open Word.

2. Find the Start option in the top toolbar, and then click Enter.

3. Then there is an "X?" Under the font size option. Style icon, which is a tool for adding superscript.

4. Now try to write an equation of a circle whose center is at the origin: x? +Y？ =R？ . Write X2+Y2=R2 first.

5. Select a "2" with the left mouse button, and then press and hold the Ctrl key of the keyboard to select the remaining two "2".

6. Finally, click "X" in the third step. Style icon, of course, quadratic can be like this, cubic can be entered like this in many cases.

Extended data:

The most basic definition of power is: let a be a certain number, n be a positive integer, and the n power of a is expressed as a? That represents the result of n times multiplication, such as 2? =2×2×2×2= 16。 The definition of power can also be extended to zero power and negative power and so on.

When inputting mathematical formulas on the computer, because it is inconvenient to input the power, the symbol ""is often used to represent the power. For example, the fifth power of 2 is usually expressed as 2 5.

Algebraic terminology: square root

Algorithm of power:

There are two algorithms for power.

The first is to calculate directly by multiplication, such as: 3? =3×3×3×3=8 1

The second is the multiplication of numbers under the power class, such as: 3? =9×9=8 1
