SOURCE: how do i use the inv log for calculations on my sharp el-531wh

Hello,

Let y=10^(x) 10 to the power of x

Take the log of both tems of the equality. You get

log(y)=log[10^(x)] where I used square brackets for clarity. But from the general properties of logarithms

log(b^(a)) = a*log(b)

Applied to our expression above

log(10^x)=x*log10

But since we are using log as log in base 10, log_10(10)=1

so

log(y)=x

We thus have two equivalent relations

**y=10^x <----> x=log(y) **The double arrow stands for equivalence.

If **y is the log of x**, then **x is the antilog of y**

Your question: With log_10 standing for logarith in base 10

pH=-log_10(c) c= concentration

Then log_10(c)=-pH the equivalence above translates as

log_10(c)=-pH is equivalent to c=10^(-pH)

The concentartion corresponding to a pH of 7.41 is

c=10^(-7.41)=3.89x10^(-8)

You enter it as follows

10[^]7.41[(-)][ENTER/=]

Hope it helps

SOURCE: can you find shift button on sharp calculator (EL-531WH) D.A.L

Hello,

On Sharp calculators, the shift key is the [2ndF] key.

Hope it helps.

Can anyone provide the steps for calculating IRR on the Sharp EL-531WH?

Mar 30, 2011 | Sharp EL-531VB Calculator

you can press the "**log" **button or the **"ln" **for logarithmic calculations. the difference is just that "ln" calculates log on base "e".

Hello,

The [2ndF] key allows access to other functions. I do not have the calculator under my nose, but I suspect under the [2ndF][LOG] you access the 10 to the power x function [10^x] or [10 to the x].

Hope it helps.
