Question about Casio Fx-992s Scientific Calculator

That depends on the make and model of the calculator. A few calculators have a logBASE or similar function which takes an arbitrary base. Most only have logs to base e (ln) and base 10 (log).

However, the log of x to any base can be calculated on any calculator with logs as either

log x / log base

or

ln x / ln base

However, the log of x to any base can be calculated on any calculator with logs as either

log x / log base

or

ln x / ln base

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**☺**

The 30XIIS only calculates logs to base e (natural log, ln) and base 10 (common log, log). However logs to any base can be calculated indirectly.

To calculate log base b of x, calculate either log(x)/log(b) or ln(x)/ln(b).

To calculate log base b of x, calculate either log(x)/log(b) or ln(x)/ln(b).

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)

To calculate the log base 2 of a value, calculate its log and then divide by the log of 2. You can use either the log or the ln keys, but be consistent. For example, to calculate the log base 2 of 16, you can calculate either log(16)/log(2) or ln(16)/ln(2).

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)

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.

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,

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

Look it's simple in the calculator the default base is 10 so when you input log 3 its log 3 base 10 so:

maybe you know in math log x base y = log x / log y . So if you need log 3 base 3 its => log 3 / log 3 (by the way its 1)

maybe you know in math log x base y = log x / log y . So if you need log 3 base 3 its => log 3 / log 3 (by the way its 1)

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 :)

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 :)
