How to play the root number A B C Thank you Urgently

jjfans01": Hello.

a+b）+c

There are many ways to type the root number ( ), and the easiest way is to type it directly from the keyboard, and the method is as follows.

Press and hold the shift button (alt key) with your left hand, press 41420 with your right hand in turn, release both hands, and the root number ( ) will come out.

Similarly: pressing 178 is the square number ( ).

Press 179 is the cubic number ( ).

215 is the multiplication sign ( ).

247 is the division sign ( ).

176 is a degree (°).

There are also many math and special symbols to play.

You might as well give it a try, hello, goodbye.

There are several ways to play the root number (root number a + b) + c:

1. In the root: the root number a + b) + c, the root number ( ) and other mathematical and special symbols have a variety of methods, the easiest way is to type it directly on the keyboard.

The method is (in any input method state), hold down the shift key (alt key) with the left hand, and then press 41420 in turn (do not press the top of the keyboard, press the right one), and then release the left hand, and the root number will come out.

2. Word 2003 inserts "root number".

Word 2003 Insert Formula.

Click where you want to insert the formula.

1) On the Insert menu, click Object, and then click the New tab.

Click the Microsoft Formula option in the Object Type box.

If you don't have a Microsoft Formulator, install it.

Click the OK button.

2) From the Formulas toolbar (toolbar: A toolbar contains buttons and options for executable commands. To display the toolbar, click Customize in the Tools menu, and then click the Toolbars tab.

Select symbols, type variables and numbers to create a formula.

3) In the upper row of the Formulas toolbar, you can choose from more than 150 mathematical symbols. In the following row, you can choose from a number of templates or frames, including fractions, integrals, summation symbols, and so on.

There are also tricks for playing other symbols, such as:

Press and hold the shift button (alt) with your left hand and press 178 to square the number ( ).

Press and hold the shift button (alt key) with your left hand, and press 179 to mark the cube number ( ).

Press and hold the shift button (alt) with your left hand, and press 215 to multiply ( ).

Press and hold the shift button (alt key) with your left hand, and press 247 to divide ( ).

Press and hold the shift button (alt) with your left hand and press 176 degrees (°).

You can also try the others, and the results will be different!

Or use smart ABC, press V, press the number, and also use different mathematical symbols.

The square difference is the formula.

a^2-b^2=(a-b)(a+b)

Root number filial piety is not a - root number B) (root number A + root number B) = (root number A) 2 - (root number B) 2 = a-b

Root number a-root number b) (root number A + root number B) (a-cavity do b) (a-b) (a+ b) (a-field judgment b) (a-2 ab+b) (a+b).

1-2√ab/(a+b)

root number A - root number B) divided by (root number A + root number B).

Root burial omen A - root number B) (root number A - root number bend) divided by (root number A + root number large number B) (root number A - root number B).

A-2 root number (ab) + b) (a-b).

This result is 0 with blindness, a-b is greater than the family and is equal to 0, b-a is greater than 0, etc

Only a-b=0 is a=b, which is 0+0=0

∵(√a+√b)(√a-√b)=a-√ab+ab-b=a-b∴√a-√b=(a-b)/(a+√b)

Square difference formula: a -b = (a-b) (a+b) Mingjiao answers for you, if you are satisfied, please click [satisfactory answer]; If you are not satisfied, please point it out and I will correct it!

Hope to give you a correct answer!

Good luck with your studies!

First, multiply the numerator and denominator by the root number + root number, and then use the square difference formula.

The process is as follows:

Proof process: set the root number a=m the root number b=n

Then m = a, n = b finches.

So m n = ab

So both sides are squared.

mn = root number (ab).

There is also the root number a=m and the root number b=n

So wild shot (root number a) * (root number b) = root number (ab).
