One of the number keys (#6) does not function; for example, if I enter a number which includes a 6, the six does not get entered

what might I do to reactivate this key?

thank you

Probably just need to resolder the switch for #6, should just need to have the soldering iron touch the solder to re melt it. worth a try.

We are asking what number, times itself, is equal to 30. Five times itself is 25. Six times itself is 36. The answer is somewhere between 5 and 6. Let's split the difference and try 5.5. 5.5 times 5.5 is 30.25. This is above 30, so let's try a smaller number, 5.4. 5.4 times 5.4 is 29.16. This is lower than 30, so we need a higher number. How about 5.45? I get 29.7025. We need a number a little higher. How about 5.47? I get 29.9209. Still need a little higher. How about 5.48? 30.0304. So it is somewhere between 5.47 and 5.48.

On a calculator, you can use the square root function. Sometimes you have to enter the number before you hit the square root function and sometimes you need to enter the number after hitting the square root function. Another way of doing it is to use the exponent function, usually with a y to the x key or a ^ key. Enter 30, hit the exponent key, and then enter 1 divided by 2 in brackets.

I get approximately 5.477225575051661134569697828008.

Good luck.

It depends on the base of the power function.

**For exponential function** use [SHIFT][LN] (e^x) followed by the exponent value. If exponent is negative use the change sign +/- key before exponent.

For a**general power**, type in the base (number), then press the [Y^x] key followed by the exponent.

For a**power of 10,** use the [Exp] key. Careful here. For example to enter 1.6x10^(-19), type in 1.6, press the [Exp] key, then the change sign key +/- and the exponent. Press [=]

**1 . 6 [Exp] +/- 19 [=]**

For natural logarithms, you can use the ln
function (2ND shift of the X key). For example, the natural logarithm of 3 is
2ND [LN] 3 ) ENTER.

For logarithms to other bases, use the log function (diamond shift of the 7 key). For example, the base-2 logarithm of 16 is diamond 7 1 6 , 2 ) ENTER. If the base is 10 (common logarithms), you can omit the comma and the second argument.

apply a dry contact cleaner over the defective key and press it many times until it becomes fine if this does not work will.

please follow me:-1- use a *****driver and get out *****s in the bottom(normally 4-5 *****)2-open the machine you will find the keyboard and many small *****s remove all with small *****driver.

3-remove key bad out and clean it with water-dry it carefully and return it back put all *****s back and test your calculator.
