### Hi, how do i use casio fx82ms to raise a figure eg. to the power of 4?There's no xto the power of y button....

There should be key marked [Y to the x] or [^]. If exponent is negative use the change sign key (-) not the MINUS sign.You will have to use the [^] key if you calculate roots of order higher than 3. Example 7th root of 353 =(353)[^](1/7)

### What is the meaning of the mathimatical expression

n mathematics, an expression is a finite combination of symbols that are well-formed according to the rules applicable in the context at hand. Symbols can designate values (constants), variables, operations, relations, or can constitute punctuation or other syntactic entities.
Any "expression" that represents a numeric value. Example: 2+2=4 or x+7=10. Actually the examples above are equations, not expressions. Expressions do not have = signs. 7a and 4x are examples.
it is a mathematical statement e.g 7=6+1 THE WHOLE THING IS AN EQUATION but the 6+1 is a expression.You can only have expression is there is an = sign
Yes the 6 + 1 part is an expression. Once you have an = sign or any of the other inequality symbols (,...) it is no longer an expression but a full math sentence

I suggest you use the Restoration Disk.

When asked click on Non-Destructive Restore. (Repair)

If you click on Destructive Restore, (Full Installation), you will wipe out all personal documents you have saved.

For example:
Files in My Pictures, My Videos, My Music, personal documents you have created, and documents you have downloaded.

Non-Destructive Restore, or Repair, will repair the basic Windows files.

If you do not have the Restoration Disk for YOUR computer, you can order it from HP Support. (HP bought out Compaq)

In the USA there is no charge for the Restoration Disk.
The shipping and handling is Not free, however.
\$17 for a 5 to 7 day ship, \$24 for a 2 to 3 day ship.

This is the toll-free number to call in the USA, (24 hours a day, 7 days a week),
1-800-474-6836

I am not familiar with support overseas, however here is the HP Support page for Worldwide,

### For instance if I have a problem of 4x+1-x=2x-13+5. how do I enter it in my T E to find wha is X

Hi,
This calculator does not have a Solve function or a solver. However this example of yours is very simple that you can do it by hand. If you do not mind I will show you how to solve it. Not everything needs a calculator.
You want to solve for x. OK
1. Start by gathering similar terms 4x-x =3x; -13+5 =-8
2. Rewrite your equation as 3x+1=2x-8
3. Make the +1 change side while changing its sign
4. 4x+1 -1 = 2x-8 -1 or 4x=2x-9
5. Make +2x on the Right hand side go to the left hand side, changing its sign in the process 4x-2x=-9 or 2x=-9
6. Divide both members by 2. This gives
7. x=-9/2 or -4.5 if a decimal result is required.
Hope it helps.

### I have a Samsung U520 and I accidentally activated NAM2. Now my phone does not work. When I try to deactivate NAM2 it asks for a password. Can you help? It needs a 4 digit code. It also states Initial...

hi sir have you done restore factory settings firstThe Nokia 2160 series hand portable CMT uses an EEPROM NAM that can be programmed directly from the standard user keypad. In order to access the
NAM, you must enter the special access code currently programmed into the
phone. Once the programming mode is accessed, NAM parameters are loaded
by entering them into the display and "storing" them to selected memory
locations. Be sure to obtain all parameters before proceeding.

EASY NAM PROGRAMMING

1. Turn on phone.

2. Enter the Easy NAM access code. Access code is: *#639#

3. Verify the display now reads "Cellular Number" and enter the 10 digit
MIN for the phone.

4. Press the softkey under the word "OK" in the display. If less than 10
digits are entered an error message will prompt you to reenter the
number.

5. Verify the display reads "Enter code" and enter the five digit SID
followed by four zeros. (Example 001750000 is a SID of 175 followed
by four zeros). An error message will display if an incorrect entry
is made. Do not add more than four zeros to the code.

Note: Change the Lock code by adding a pound sign and new lock code after
the code. (Example: 001750000#7788. Lock code = 7788).

Change the Language code by adding a pound sign (#) and new
language code after the code. (Example: 001750000#2. Language = 2)

Language Code: 0 (default) = English, 1 = French, 2 = Spanish,
3 = Portuguese

Change the Lock code and Language code by separating each set of
numbers by a pound sign. (Example: 001750000#7788#2). The SID =
00175, Lock code = 7788, Language = 2 (Spanish).

6. Press the softkey under the word "OK" in the display.

7. The display will tell you t
