Yes it can be keyed in.
To enter the X, use the ALPHA followed by ). To enter the = sign, you use [ALPHA][CALC].
To use the calculator to SOLVE an equation you must enter the equation, then press [SHIFT][CALC] to (SOLVE). You will be prompted to solve for X. Follow it from there.

As to the case you show, the constant terms will drop and you are left with 26X=0, and the solution is X=0.

Note: The calculator cannot do algebra with letter symbols. It does not have a Computer Algebra System or CAS.

### My router will not connect to the internet

teps:

1. Connect PC to one of the 4 LAN ports of ur Netgear via LAN cable (DO NOT connect it to ADSL router right now).
2. Change LAN IP address to something other then 192.168.1.x. like suppose 192.168.2.1. To do that click on LAN IP Setup....apply.
4. Right click on the connection icon in sys tray and hit repair.
3. Now connect WiFi router to ADSL modem as earlier.
4. Run WiFi setup Wizard.

This should get you started.

Ok, here are the steps to make the connection secure.

3. Uncheck Enable SSID broadcast. Apply
4. Click on Setup Access List
5. Turn access control on. Add ur wireless cards mac id to the allow list. Apply

1. Go to Setup>>Wireless Settings. Here notedown the connection name(SSID) since you'll be needing it later.
2. In security options, choose WPA-PSK
3. Put in a passphrase.
4. Put in the key lifetime as 15min. Apply.

Ur net connection will stop working after this coz u have to configure ur laptop.

5. Now if ur using a laptop with intel centrino, then go to Start>>Intel Pro Wireless. If u were using the windows client earlier, switch to this one.
6. Make a new Profile. Put in the connection name (SSID). Click next.
7. In the Network Security option, choose WPA Personal from the menu and TKIP from the Data Encryption Menu. Put in ur passphrase below. Save and click on Connect. U Should be back online now with a secure connection.

Let me know how this goes when you try it and if you have any questions on this, please tell me. thanks.

### Can it solve 8^x=4 ???

Hi,
You can use algebra to solve it.
Use the fact that 4 =2^2 and 8=2^3 and substitute in the equation
(2^3)^x =2^(3*x)
Then 2^(3*x)=2^2
By equating the exponents
3x=2 and x=2/3

Using the solve( function
With the calculator physical keys between square brackets, and the SHIFTed or ALPHA keys between parentheses, type in the following
8 [^ ] [ALPHA] [ ) ] (X) [ALPHA][CALC] ( =) 4 [SHIFT][CALC] (SOLVE)

Once the foregoing command entered press [=]
Display shows Solve for X on top line and probably 0.000 on bottom line.
Press [.] 5 to give 0.5 as a guess for the value of x
After a moment the calculator returns with the solution.
The display shows three lines
1st Line: 8[^] X =4
2nd Line: X= 0.66666666
3rd Line : L-R =0.

Your solution is 0.6666666. In fact the exact solution is 2/3.

Hope it helps.
Thank you for using FixYa and for rating this solution.
