Using scientific Calculator for Logarithms?

Question

I need to enter Log 2 with a base of 6, how do I do this on a scientific calculator?

Answer 1

Use this formula:

log_b a = (log_c a) / (log_c b)

where c is any other base. Use whatever base your calculator provides, compute log 2 using that base, and divide by log 6 using that same base.

Answer 2

first, u should know that the "log" on calculator generally stands for " log x(a positive real number) with base of 10".


so to get value of "log 2 based 6", just enter ("log"+2)/("log"+6).

Answer 3

Hi:

Try this: Log (2)/Log(6) =

this should give you the answer to the log(2) base 6

Answer 4

remember that:

LOGbase a (b) = LOG base c (b) / LOG base c (a)

So use the log base 10 or the log base e key on your calculator to compute log of 2 and log of 6 and divide them. Just use the same log key.

Answer 5

Easy. Take log 2 and divide by log 6.

Answer 6

3)9

Answer 7

Log base b of x is ln x / ln b.

Thus, Log base 10 of x is ln x/ln 10.

Thus: 2 [ln] [/] 6 [ln] [=]

Or use [log] in place of [ln].

Answer 8

Check the User's Manual that came with the calculutor. That will explain how to do it.

It depends on the calculator.

Good luck! :)

Answer 9

log(6)2 = (log(2))/(log(6))

Answer 10

Google "change of base rule" you might find something usefull.
