Question about Office Equipment & Supplies

There is nothing to solve. Just calculate it on a scientific calculator that has log key.

From the screen below, choose your case as your statement is ambiguous (to me). Question: What is the purpose of carrying the 1 in the denominator of the argument of the logarithm function?

Always simplify as much as possible.

Press LOG 3 ENTER.

The LOG key on the keyboard gives you base-10 (common) logs while the LN key gives you base-e (natural) logs. If you want the log to another base you can use the logBASE function found in the catalog.

I calculators __you can't__ change or set the base of 'log' is __default 10__ so you need to know these:

log x (base y) = log x / log y

when log x it's automatic log x (base 10) here some examples:

log 8 (base 2) = log 8 / log 2

log 27 (base 3) = log 27 / log 3

and the base it's default 10 again, and that is how you need to use it in calculators(no bases), and here the explanation to this:

log x (base y) = log x (base 10) / log y (base 10) = (log x / log 10) / (log y / log 10) = (log x / log 10) * (log 10 / log y) = log x / log y

here so other stuff about 'log' :

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

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

Hope it's helped**☺**

To calculate the log base b of x, divide the log of x by the log of b. You can use either the common log (log) or natural log (ln) as long as you use the same one for both.

For example, to calculate the log base 5 of 10, divide

log 10 by log 5

or

ln 10 by ln 5 .

Either way you should get about 1.43 .

For example, to calculate the log base 5 of 10, divide

log 10 by log 5

or

ln 10 by ln 5 .

Either way you should get about 1.43 .

Calculate the log (base 10) of the number, then divide the result by the log (base 10) of the base.

For example, to calculate the base-3 log of 9, calculate the log of 9 to get 0.954 . Divide that by the log of 3 (about 0.477) to get 2.0 .

Since 9 is 3 squared, the log base 3 of 9 is 2, as we just calculated.

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)

For example, to calculate the base-3 log of 10, calculate

log(10) / log(3)

or

ln(10) / ln(3)

4726 seems to already be on base 10

it's 4*10^3 + 7*10^2 + 2*10^1 + 6*10^0

it's 4*10^3 + 7*10^2 + 2*10^1 + 6*10^0

Calculate it the same way as on most other calculators, using the relation

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

In words, calculate the log base 10 of x divided by the log base 10 of the base. You can also use the natural log function instead of the common (base 10) log--just be consistent.

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

It's simple here some logs:

log x base y = log x / log y

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

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

you just need to know that the default base of log in calculators is 10, so log x mean

log x base 10 = log x / log 10,

so write log x / log y for log x base y example:

log 8 base 2 = log 8 / log 2 that is how you write it on calculator, hope it was helpful

log x base y = log x / log y

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

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

you just need to know that the default base of log in calculators is 10, so log x mean

log x base 10 = log x / log 10,

to do logarithms with other bases, use change-of-base.
let's say you want to do log base 5 of 25. for clarity i'll write this as log(5) 25.
you would have to do log(10) 25 / log(10) 5 to get 2.
key sequence:
[LOG], 2, 5, ), / (divide), [LOG], 5, )

I don't get it but here some help with logs:

log x base y = log x / log y (when log x is default base 10 in calculators) and

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

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

the bases is default 10

hope it's helped

log x base y = log x / log y (when log x is default base 10 in calculators) and

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

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

the bases is default 10
