1.393 is the correct answer for the natural log of (1/37 + 4). I believe you want natural log(1/37) + 4, which is .3891 .

Watch those parenthesis. By putting the "+4" inside, you're doing the addition before calculating the log. You want to calculate the log and then add 4.

I am having trouble figuring out how to enter problems to find logarithmic functions

Let me give you a general recipe to familiarize yourself with any calculator, if you are averse to reading the manuals.
Most function will work in one of two ways.
1st way
Enter the number, then press the key,; the result is displayed.immediately.

Second way
Press the function key ( a left parenthesis may be displayed) enter the number (close the right parenthesis if there was a left one) press the = or EXE or ENTER keys.

Try the two ways described above to calculate the following values. The answers are given. Here log is he decimal logarithm and ln is the natural logarithm.


log(10)=1 (= number of zeros after the 1)
log(100)=2. (= number of zeros after the 1)
log(1000)=3 (number of zeros after the 1)
log(10000)=4 (number of zeros after the 1)

How do i use log functions on the HP 39g+. For instance i want to use log10 1000 which should equal 3 or 3^5=243 so log3 243 should equal 5. If i press log the calculator shows: log( If i...

To calculate the common log ( LOG base 10) of a positive number, just press the LOG key, the one above the blue Division key, then enter the number and close the right parenthesis. Press the ENTER key to get the result.

If you want to calculate the log in a base other than e (natural) or 10 (decimal) logarithms, you need to make use of one of the equivalent formulas below

log in base a of a number b
log_a(b)=log_10(b) / [ log_10(a)] or
log_a(b)= ln(b)/ln(a)

How can I calculate Log2 2.5 on my calculator.. since everytime I start entering it i start by pressing log and right away it says ERROR.. by the way the 2 right after log is suposed to be a little 2.

First of all, to compute the log of a number, enter the number first then press the LOG key.

Second, to compute the log to a base b other than e or 10, use the relationship
logb(x) = log(x) / log(b) = ln(x) / ln(b)
You can use either the common log (log) or the natural log (ln), as long as you're consistent.

So, to calculate log2(2.5), press
2 . 5 log / 2 log =
2 . 5 ln / 2 ln =

What button do you push on the TI-86 calculator to do the inv log function?

For the inverse natural log, press 2nd LN. For the inverse common log, press 2nd LOG.

For example, to calculate the inverse natural log of 2, press 2nd LN 2 ENTER and you'll get about 7.389 .

How can i get logarithms on the calculator

For natural logarithms Press [2nd][X], enter a positive number, close the right parenthesis and press [ENTER]. If the number is decimal the result is displayed as a number. If the number is integer, put a decimal mark at its end to have the result displayed as decimal.

For decimal logarithms use the ALPHA keyboard to enter the log( command, complete the argument and press ENTER

If you want to calculate log in base a of number b type log(b,a).

How do I enter a logarithmic function like log base 2 of 64 to equal the answer 6? Thanks!

You can calculate the logarithm to any base by using the relationship

  logb(x) = log(x) / log(b) = ln(x) / ln(b)

Thus, if you calculate log(64) / log(2), you will get 6, and the same with the natural logarithm.

I need to know how to put an exponent in square root form

To get an exponent press 2nd then LN or LOG

LN is natural logs, so entering 1 then 2nd LN gives you the natural exponent of 1 which is.2.71828....pressing LN gives you the natural log of 2.71828.... which is 1

LOG is logs to base 10, so entering 1 then 2nd LN gives you the 10 to the power 1 which is.10, pressing LOG gives you the log of 10 which is 1 again
