Use the rules for exponents and you will calculate it by hand

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

To enter powers of 10 use the short-cut key [EE]

For example to enter 6.02*10^23 type in** 6.02* [EE] 23**. When you use the EE key, the base (10) should not appear.

(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3

That will be because the photo pack is stale. The chemicals it uses do not last forever, there is no fix for this.

Many will be, given that they're all past their expiry date and none have been manufactured for two and a half years. Usually the main problem is that the battery built in to the photo pack is either flat or only has insufficient power to get through all ten photos.

As a rule, packs kept in the fridge will have freshest chemistry but almost always a dead battery, and those kept in warm conditions will have stale chemicals and maybe a battery which will last the entire pack. Not much use though...

the way i enter my equations is a bit different from what you're doing, i use the fraction button to do division problems, i just feel it makes it easier to read.

anyway, the fraction button is on the far left, 3rd button down (it looks like a white box on top of a line, and below the line is another empty box). press that, and you can type 1.0x10^-14 on the numerator.

it seems that you haven't discovered the EXPONENT button. that button is on the same row as the fraction button, it looks like an x with a white box next to it. press that once you've typed out "1.0x10", and then type -14. the negative button btw is below the fraction button, and looks like this: (-)

press the right arrow twice on the circle thingy at the top of all the keys, and that'll advance you to the denominator. type 2.0x10^-5, using that nifty exponent key. press the equal sign and it'll solve it for you, all in scientific notation (the answer is 5x10^-10). the problem with this calculator is, it won't expand that answer for you with all the decimals and everything, but if its chemistry that shouldn't be a problem.

also, you can certainly use the "x10^x" button on the very bottom of the keypad (its next to the decimal button). by using this key, you won't have to press the exponent button since you can just type in the exponent directly next to the 10.

as for that negative log of 5.6, just input the negative, the log button is right next to the exponent button, and your number and yeah....it's that easy :]

i hope you like this caculator, it has so many functions (have you seen the size of the manual??)

good luck on your chemistry test!

Hello,

If I guessed right you are talking about the Chemistry notion of the pKa

Let the equilibrium constant be Ka =1.8x10^(-5). Then by definition pKa=-log(Ka) , log in base 10

pKa = - log(1.8x 10^(-5))

First set [MODE] to [COMP] by pressing [MODE] 1.

** [LOG] [(] 1.8 [x] [SHIFT] [10 to the x] [(-)] 5 [)] . [(-)]**

The [(-)] key is the change sign key : a small - between parentheses. The last [(-)] sign in the expression takes the negative of the whole calculation to obtain the correct value of the pKa.

The value you should find for the above exemple is 4.74

Hope it helps.
