SOURCE: how do i perform the calculation of log (base 2)

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 :)

I have a TI-84 and when i put a negative number it appears Ans before how can change that?


Use the (-) key to the right of the decimal point key when entering a negative number. The - key to the right of the 6 key is for subtracting something from something else. In order to subtract from something, if you don't specify anything then the calculator uses the previous answer as designated by "Ans." The same thing happens with the + key for example, because it adds something to something else.

How to get ans log of bases other then 10


You can calculate the log to any base B by dividing the base-10 log by the log-base-10 of the base B. You can also calculate it by dividing the natural log by the natural log of B.

For example, to calculate the base-3 log of 10, calculate
log(10) / log(3)
or
ln(10) / ln(3)

Hi, i would like to know if you set your calculator to "float 3" so that it gives results in the form of x,xxx will the calculator when i calculate further using previous results use the float...


The display setting affects ONLY the display of the number. The calculations are always carried out with full precision. So in your example, further calculations are carried out using 3.141592654 no matter what the display says.

How do I insert exponent to my calculator?


To enter a power of ten, use the *10^x key, located on the bottom row of the keyboard between the decimal point and the Ans keys. For example, to enter 1.2 times ten to the third, press 1 . 2 *10^x 3

To raise a number to a power, use the x^* key, located just below the big round cursor pad, between the x^2 and log keys. For example, to calculate 2 raised to the fourth power, press 2 x^* 4 =

How do you calculate the inverse log.


Raise the base of your log to the power produced by the answer.

Example: If ln(x) = y, raise e (base of the natural logarithm) to the y to get x = e^y
Example 2: log(x) = y - x = 10^y

So if log(x) = 2, x = 10^2 = 100

How do i perform the calculation of log (base 2) 8? The answer should be 3....that is it is the inverse calculation of 2 cubed =8. Can any one help with the log calculation?


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 :)

Memory and memory recal


The STO> button just above the on/off button is your memory store initializer.
example: 2x + 53 STO> y
stores "2x + 53" in a variable named "y".
To recall, just hit y and enter. In fact, if you type an equation like 3y^2 - 4y it will insert the data in for every "y" and give you:
(2x + 53)(6x + 155) as an answer.
To clear the memory:
DelVar y or F6 (2nd+F1) and clear all w/ single character names.
To recall a prevous answer, 2nd+(-) or type ans(1) for the last answer. You can also type ans(2) for the 2nd to last answer & so on.
