2 squared symbol can be inserted in different ways in different devices. In an android smartphone, 2 squared symbol is inserted by longpressing the "2” button from numbering keypad. On Mac, iPhone, and iPad, you can insert 2 squared by typing ^2. In Chromebook, you press “Control” + “Period” it will change the format to superscript.
1. What is 2 squared symbol?

In mathematics, the 2 squared symbol that are represented by “2” is an arithmetic operator that exhibits the multiplication of a specific digit with its self. If there are some signs along with the digit, those signs are also multiplied.

When a number is multiplied by itself, this function is referred to as squaring of that number. When you are dealing with exponential operations, you come across the squaring of numbers. It can either b 2 square, 3 square, and so on.

In simple words, squaring off a digit or a number means that the number or digit is raised to the power of 2. Squaring is just the inverse of the square root. When you raise a number or digit by the power of 2, it means you have squared it.
2. Basics of squaring function

While getting into the basics of the squaring function that is an important part of geometry or trigonometry, squaring is simply the multiplication of the digit or number with itself.

When you multiply the number by itself, it means that you have squared it. For example:

The symbol 22 simply means that you are multiplying 2 with 2 (2×2). This is a general rule that applies to all. You can represent it like this:
n2 = n × n
 While n is representing any number. An interesting factor associated with the squaring is that if you put in the additive inverse of that number shown by n, it will result in the same number. For example:
n2 = ( n)2

2 Squared symbol using Keyboard shortcut
One of the most convenient ways to add the squared symbol is that:

You have to hold the Alt key from the keyboard and while holding it, you will type 0178 by the numbers present in the number pad of the keyboard.

If you want to add 2 squared by a keyboard shortcut, make sure you are not pressing the abovementioned numbers from the upper row of shortcut keys.

You will have to press the numbers from the number pad present on the right side of the keyboard side. Hence, the keyboard shortcut for adding the squared symbol is Alt + 0178 and it will result in (²).
2 squared symbol on Microsoft word

Most of the time when you are using a laptop or computer where you need to add symbols is the Microsoft word and also the google docs.

So, while using Microsoft Word or other word processors, you can come across the special supporting characters such as the subscript or superscript (x2 or x2 respectively).

Now, here is the method to add the square symbol while composing a document at the Microsoft window.
First method

If you look at the front group just below the tab named “Home”, there are two buttons, one for subscript and the second for the superscript.

If you click the superscript symbol that is represented by x², it will automatically appear as a squared form. Either you want to put 2 squared or 3 squared it’s in your hand now.
Second method

Another way to add a squared symbol is that first, you write the number to which you want to add a 2 squared or any other square.

Now, select the number that you have written and then click the superscript button to add a squared symbol. Now click it again to be in normal form again.
Third method

There is yet another way to add the 2 squared symbol in Microsoft Word. In this method, you have to use the shortcut keys. It can be simplified as:

Ctrl + shift + the sign of + i.e. press and hold the ctrl and shift and then press the “+” key present at the right side of the keyboard. It will result in the same squaring as was done by method 1 and 2.

However, these ways are only applicable to Microsoft word. You will have to use different commands while composing the document at some other place on your laptop.

For example, if you use these shortcuts at chrome browser, it will just zoom the window that is an entirely different thing.
For google docs

Frequently asked questions
There are several questions related to squaring that need to be justified. Some of those questions have been answered below:
1. What does 3 square mean?

3 squared is also referred to as a cube. It can be inserted similarly as done for 2 squared symbol.

In contrast to the 2 squared in which is the number is multiplied by itself for one time, 3 square or Cube means that the number is multiplied by itself three times. The symbol for 3 squares is (³).
2. How do you type 3 squared on the keyboard?

Press Alt key and simultaneously press 0178 in number keys and release alt.

After releasing alt, superscript 2 will appear.

Similarly, if you have to add 3 squared, then press 0179. A superscript 3 will appear.

This process can be applied anywhere in the Windows or online and even in the Microsoft world.
3. How do you type x2 on a laptop?
To type 2 squared symbol or x2, you can proceed in the following way:

First, you have to type “x” and then press Ctrl + Shift + P

Now type 2 and the same keys (Ctrl + Shift + P) again.

It can be added by simply clicking the superscript icon in the upper bar.
4. How do you type a superscript (squared symbol)?

For typing the superscript, you simply have to press Ctrl + Shift + + sign from the keyboard.

It can be elaborated as, click and keep holding the ctrl and shift, then click + symbol from the upper line of the keyboard.

Pressing the same keys will result in the normal text.
5. What does superscript mean?
A superscript is regarded as a number or letter that is lying slightly above the normal line of typing. Its size is comparatively smaller than the normal text.
It is used to represent the power of some number or letter such as 2 or 3 squared symbol that is used in mathematics or more precisely in algebra.
Opposite to the superscripts, the subscripts appear just below the line of typing.
Conclusion
2 squared symbol is used in algebraic mathematics most of the time. It can b inserted in different ways on different devices.

In android Smartphone, a “2 squared” symbol is inserted by longpressing the "2” button from the numbering keypad.
