Question about Texas Instruments TI-83 Plus Calculator

I am having problems getting the correct answer to the above problem. I think that I am not entering the problem into the caluculator properly. How do I enter log 1.9 divided by 4 log 1.0175 into the TI-83 Plus?

Hi,

I assume 13m/2 is the radius of the sphere and you are trying to calculate the volume of the sphere.

The first thing we have to think of is BEDMAS, the order of operations, as some calculators do them correctly, while others do not. Let's be safe and do the BEDMAS manually so we know we will get the correct answer.

B - brackets - enter 13/2 in the calculator - hit enter

E - exponents - with the answer from the first line in the calculator, use the hat key (^) or the y to the x key to raise this to the third power (exponent 3).

M - multiply - with the answer from the line above, multiply this by pi or use what you are instructed to use or use 3.14159, then multiply by 4 and divide by 3.

You should have your answer.

Good luck.

Paul

Nothing of the sort. Just locate the EE key. You access it by pressing [2nd][x^-1]. It is the one below the [sin] function key.

To enter Avogadro's number

Key in

6.02 [2nd][x^-1] 23 [=/Enter]

If you divide by that number just enclose it between parentheses to ensure correct calculation.

You can also enter it as described 4 lines above, press the = key. The number will be displayed. To divide by it, press the [x^-1] key and its reciprocal will be displayed ready to be multiplied.

That's the answer I get for

30 times log of 1/2 times 83 divided by 8000

or

30 x log(1/2) x 83 / 8000

Are you sure you have the problem specified correctly?

30 times log of 1/2 times 83 divided by 8000

or

30 x log(1/2) x 83 / 8000

Are you sure you have the problem specified correctly?

Is the original problem (log 10,000 - log 1,000) / (4 log 1.0125) ? If so, press

( 1 0 0 0 0 LOG - 1 0 0 0 LOG ) / ( 4 * 1 . 0 1 2 5 LOG =

and you should see the expected result.

( 1 0 0 0 0 LOG - 1 0 0 0 LOG ) / ( 4 * 1 . 0 1 2 5 LOG =

and you should see the expected result.

To enter an exponent, positive or negative, use the EE (Enter Exponent) key (the shifted function of the , key just above the 7 key). Do 5 2ND [EE] (-) 1 0 / 5 2ND [EE] (-) 1 0 ENTER and you'll see 1.

What I think you're doing (I can't be sure without seeing your keystrokes) is calculating

5*10^-10/5*10^-10 which is interpreted as (5*10^-10/5)*10^-10, which indeed is 10^-20.

Press the keys:

. 5 8 * 1 2 . 0 1 x^-1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER

and you should get 2.9E22. Do you get something different?

* is the multiply key on the right, between divide and subtract.

x^-1 is on the left, below MATH.

EE is the 2ND function of the , key, just above the 7.

Another way to calculate this is:

. 5 8 / 1 2 . 0 1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER

This should give you the same result.

. 5 8 * 1 2 . 0 1 x^-1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER

I think I'm reading this correctly. In your exponent, you are dividing 23 by 206. If so, enter in the calculator the following way:

6.02 x 10 ^(23/206) and then the enter/= key. You should get an answer of 8. The ^ key is 4 keys above the "on" key. You must use parentheses around the fractional exponenet

Yes look you can't enter the base in calculators it's default 10 so use:

log x base y = log x / log y

log (x*y) = log x + log y

log (x/y) = log x - log y

so instead of log 8 base 2 input log 8 / log 2 it's easy

hope you understand :)

log x base y = log x / log y

log (x*y) = log x + log y

log (x/y) = log x - log y

so instead of log 8 base 2 input log 8 / log 2 it's easy

hope you understand :)

Proper fraction e.g. 3/5, input 3, divide, 5, =, answer 0.6

Improper fraction, either enter as improper fraction, or enter the whole number first, then +, then the proper fraction as before, then =.

E.g. 8/5 which is "1 and 3/5': enter 1, +, 3, "divide", 5 =, answer is 1.6

Or, just 8, "divide", 5, same 1.6 answer. Why go to mixed number first?

13/5 which is "2 and 3/5", enter 2, +, 3, "divide", 5, =, answer is 2.6. Or, just 13/5, same answer
