How to i raise e to a power


That is the exponential function. Look for a key marked [LN] (the natural logarithm). The exponential function e^(x) shares the same physical key as the natural logarithm.
You access one function directly (marking on surface of key) and the other with [2nd] LN

5000e to the (0.08)power time (2)


On this calculator the exponential function requires the argument be entered first. To calculate the exponential of a number, you enter the exponent (0.08) then press [2nd][LN].
For your calculation, you should calculate e^(0.08) then multiply the result by (5000x2=10000). The result should be 10 832.87068

If an equation would require dividing by log ( which og course can't be done) what button is used to fulfil that equation?


Of course you can divide by a log. As an example, to divide 2 by the log of 3, press
2 / 3 LOG =
To divide 2 by the natural log of 3, press
2 / 3 LN =

Using the correct key combination to determine inverse log


Hi,
Sorry to contradict you but there are many types of logarithms, the most important ones are
  1. the common logarithms (log in base 10),
  2. the natural logarithms (logarithms in base e)
  3. the binary logarithms (logarithms in base 2)
On calculators, the common logarithms are labeled [LOG], and the natural logarithms are labeled [LN].

The inverse function of the natural log function is the exponential (e^(x)), and the inverse of the log in base ten function is the function ten to the power of. It is called (sometimes) the antilog

Ex:
Question What is the antilog of 3.5678?
Answer The antilog of 3.5678 is 10^(3.5678) = 3696.579068
Verification: log(3696.57908) =3.5678

Hope it helps.

Reposting! exponential and log equations


Use this entry sequence:

4 LN / ( 4 LN - 2 X 3 LN ) =

or this one which evaluates the divisor first

4 LN - 2 X 3 LN = 1/x X 4 LN

CAn't find the inverse log on the calculator


Press "2nd LN" which gives you the exponential (inverse natural log) of 7.41 = 1652.426....

Pressing LN will give you back 7.41

Same procedure to use logs to base 10, use LOG and 2nd LOG

The e to the x button


If you mean (e to the power x) minus 4, where x = -1, the key sequence would be:

1
+/- (above 3 key)
2nd
LN
-
4
=

Result is -3.63212.....

If you mean e to the power (x-4) where x = -1 again, it's:

10.0067379....
+/- (above 3 key)
-
4
=
2nd
LN
