Use the log function (common logarithm). See screen capture for markings on key.

To evaluate the negative of a logarithm

Enter the number (argument) of the logarithm

Press the = key to have it calculated.

While result is still displayed, press the sign change key or (+/-).

Beware that -log(number) is not necessarily a negative value.

Another way to calculate -log is to use the relation

log(1/a)=-log(a) .

What does it give you? What is this 10exp11?

If you want to enter 7.8X10^11 type it as 7.8[EE]11. [EE] is the key [Exp[, or [EE] or [x10X]. The EE is a short cut for *10 to a power. The 10 must not be appear in the expression entered.

Use the shifted function of the appropriate log key (log for common (base 10) log/antilog and ln for natural (base e) log/antilog). For example, to calculate the common antilog of 2, press SHIFT log 2 = and to calculate the natural antilog of 2, press SHIFT ln 2 =.

Use the "log" key in the third row of the keyboard. This is for the common (base 10) logarithm. The "ln" key next to is for the natural (base-e) logarithm.

Reset the router and log in on the web page 192.168.0.1, and log on to input a new wep2 key.

Resetting is achieved by pressing the small button at the back of the router, for 2-5 seconds (between power input point and ethernet cable).

The light for the internet on the face panel should temporarily show red and then green. When all lights are green, you can then log on as admin (without password).

You can't it's default 10 so learn this logs:

log x base y = log x / log y

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

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

so just divide the logs

hope it helps

log x base y = log x / log y

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

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

so just divide the logs

hope it helps

Like you maybe know in math (I know!) log x base y = log x / log y

so what you need its just input your number (x for example) and log it, than divide log x by log 2.

just: log x / log 2. (by the way in calculator the meaning of log x is log x base 10 the default base is 10)

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)

Look the calculators has a default base 10 and you can't change it but you may learn this:

log x base y = log x / log y

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

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

so instead input log 8 base 2 you need to input log 8 / log 2

your example answer is about 0.919... if i get right what did you write.

Glad to help :)

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 :)
