When you say...
If i solve first (17/10)
...I guess you mean 'evaluate'
I'm not sure what you mean when you say...
if a build a question
Do you mean when you use it in an equation? What's the equation?

Hello to all youI am new in the group and in the HP50gAnd i need one help ;Look i have 10^(17/10)If i solve first (17/10), the result it is ok , but if a build a question as is the result is wrongCan you help-me ?Thank youWagnerSao Paulo/Brazil

Ok Mister Donyes if i solve first ( 17/ 10 ), and then i make 10^1,7 ok rightIf i make 10^(17/10) and solve it is wrongThe equation it is 10^( dBm/10 )Thank you by allWagner

No, you can't get miliwatts. There are no miliwatts in 10^(17/10), you must get some numeric result.
Put 10^(17/10) into the calculator and press the EVAL key. What do you get?

Ok Mister DonLook the equation is: milliWatts = 10^(dBm/10) ok !What i made to solve it , i put 1*, look:1*10^(dBm/1'0)Example 50mW:1*10^(17/10)=50mWThe secret it is put 1 to multiplicate the rest of equationI spend more time to solve it !Do you confirm it ?I thank you now by the Big help of me !73 de PU2RPDWagnerSao Paulo- Brazil

1*10^(17/10) = 50.1187233627
and
10^(17/10) = 50.1187233627
Do you get a different answer? If yes, what is the wrong answer you are getting?

Hello Mister DonIn the second situation : only 10^(17/10) the calculator answer to me 10,10sqrt 10^7I do not know the simbol (, ) [ coma ] in the answer ?What do you made to make the same results ?Wagner

----- Original Message -----From: Don HartSent: Saturday, August 08, 2009 6:08 PMSubject: Re: [50g] HelpI don't understand how you got 10,10sqrt 10^7 but try this. Type in each of the following and press ENTER.
-51 CF
-105 SF
This changes the flag settings. The first one Clears Flag -51 and changes the fraction mark from "," to "."
The second one Sets Flag -105 and changes from exact mode to approximate mode. That's probably what you want if you need to have answers in floating point. At the top you'll see R= (or C=) change to R~ (or C~). You can make the change directly by **holding** the right shift key (above the "ON") and pressing ENTER (-->NUM). Do it again and you're back in exact mode. If you press/release the right sift key then press -->NUM it will convert the 10*10sqrt^7 to 50.11...
You can also change your flags by going to MODE --> FLAGS. But don't make many changes at first, until you understand better what they do.
That should get you going.
