How do i solve log base 2 times x-10 plus log base 2 times x-3 minus log base 2 times x equals 2


Rephrase the question please. It makes no sense, in particular what are all those TIMES for?
Combine all the logs using the rule log_2(a)+log_2(b)=log_2(a*b)
You get
log_2((x-10)(x-3)/x)=2=log_2(4)
Thus
(x-10)*(x-3)/x=4
Convert it to a quadratic equation (x^2-17x+30=0). the solutions are x=2 and x=15. That should not be too difficult to factor out 5*2=30 -15-2=-17.

How do i use log functions on the HP 39g+. For instance i want to use log10 1000 which should equal 3 or 3^5=243 so log3 243 should equal 5. If i press log the calculator shows: log( If i...


To calculate the common log ( LOG base 10) of a positive number, just press the LOG key, the one above the blue Division key, then enter the number and close the right parenthesis. Press the ENTER key to get the result.

If you want to calculate the log in a base other than e (natural) or 10 (decimal) logarithms, you need to make use of one of the equivalent formulas below

log in base a of a number b
log_a(b)=log_10(b) / [ log_10(a)] or
log_a(b)= ln(b)/ln(a)

If i needed to enter log 5 to the base 3 into my calculator what buttons would i push?


You can calculate the log of x to any base b by calculating log(x)/log(b) or ln(x)/ln(b). So, to calculate log 5 to the base 3, press
LOG 5 ) / LOG 3 ENTER
or
LN 5 ) / LN 3 ENTER

How can I use the Log function on my calculator?


Hi ;

for log base 10 use the the "log" key

example :

log(2) + log(3) = log(6)

enter 2 press the log key you will get 0.30102999 press the '+" key than 3 log you should get 0.47712125 for it Press the "=" or enter and you should get 0.778151250 for a answer than press inv or 2nd log and you should get 6 for a answer

and that all there is to it

I'm trying to calculate base number equation


Hello,
You are victim of a confusion between terms. Base-n calculations are calculations using various numeration systems (bases) : binary (2), octal(8) hexadecimal (16) and decimal (10). What you want is how to calculate powers, logarithms, exponentials and these have also the notion of base; Log in base 10 is the common log, whereas natural logarithms, are logarithms in base e.
Back to your exemple: 5 times 5 and raise the whole to power 3?
In that case [(] 5 [x] 5 [)] [^] 3 or [X to the 3] if you have such key or
25 [^] 3, because 5x5 = 25

5 times (5 raised to power 3)
5[x] [( ] 5 [^] 3 [)] or 5 [^] 4 because of the rules about products of powers with the same base.

Hope it helps.

Using logs


Here something that would help you:

log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y

so log 24 base 2 it's log 24 / log 2 etc.
and if i get right what you wrote x= 10 ^ ( 3 * (log 5) ) if no inverse it it's easy really Hope it's helped you.

How do i use the inverse log operation on the TI-84


The problem is simple. You're trying to get an [H+] concentration which is obviously going to have a value of some number times ten raised to a negative power. Therefore, you have to insert the negative value of the pH into the 10^(x). When you insert said negative number you will come out with the right answer.
i.e.
The pH of a sample of human blood was calculated to be 7.41. What is the [H+] concentration of the blood?
10^(-7.41) = [H+]
[H+] = 3.9 E-8  
(the answer should only have two sig. figs because the pH has two digits after the decimal.
