I assume you want to round it to the nearest thousandth.

Step 1 - identify the thousandths column - going to the right of the decimal are tenths, than hundredths, than thousandths

Step 2 - check the number immediately to the right of this column

Step 3 - if this number is 5 or greater, add 1 to the thousandths column

Step 4 - if this number is 4 or less - no nothing

Step 5 - delete all numbers to the right of the thousandths column

In this case the 8 is greater than or equal to 5, so we add 1 to the 6 to get 7 and then delete all the numbers to the right.

I get 7.247.

Good luck.

Step 1 - identify the thousandths column

Step 2 - identify the number immediately to the right of this column

Step 3 - if this number is 5 or more, add one to the thousandths column. If this number is 4 or less, leave the number in the thousandths column

Step 4 - set all number to the right of the thousandths column to zero.

I get 0.1880, which we normally write as 0.188.

Good luck.

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.

Step 1 - identify the thousandths column - going to the right of the decimal point, we have the tenths column, the hundredths column, and the thousandths column

Step 2 - check the number immediately to the right of this column

Step 3 - if this number is 5 or more, add 1 to the thousandths column - if this number is 4 or less, don't add 1 to the thousandths column (leave it alone)

Step 4 - erase all the numbers to the right of the thousandths column.

In this case, the number in the thousandths column is 4. The number immediately to the right of it is a 0. Since the 0 is 4 or less, we don't add 1 to the thousandths column. Now we erase all numbers to the right of the thousandths column. I get 22.524.

Good luck.

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)

The 30XA only has logarithm functions for base e and base 10. However, you can calculate the logarithm to any base by using the relationship logb x = log x / log b = ln x / ln b

To calculate log3 of 9, press

9 LOG / 3 LOG =

or

9 LN / 3 LN =

To calculate log3 of 9, press

9 LOG / 3 LOG =

or

9 LN / 3 LN =

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

LOG 5 ) / LOG 3 ENTER

or

LN 5 ) / LN 3 ENTER

The calculator does logarithms only to base 10 (common) and base e (natural). You can calculate the logarithm to any base by using the relationship logb(x) = log(x)/log(b) = ln(x)/ln(b) .

So, one way to calculate this is as follow:

5 ^ ( LN 3 ) / LN 5 ENTER

Note that the calculator automatically opens the parenthesis when you press LN, and you don't need to close them all before pressing ENTER.

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
