(-2x^2)*(5x^6) I'm not sure what I should do here it is supposed to be simplified but I don't think that I can just combine the x^2 and the x^6 because of the ()'s I'm sorry i copied the problem down incorrectly the question in my previous post should have been 15x^5*y^6

15^5*y^6 over 7xy^4 all this was in ()'s and its to the power of 4 i think that it is 22*x^16*y^8 is that right?

how do you find out how much memory is used/free/total on your computer? (using windows xp)

I had an idea recently. I tend to drop man small metal components and instead of looking for them i would prefer to just flick a switch on an electromagnet. so how would you build an electromagnet capable of picking up small metal components from 5-10 feet and what would such a magnetic field would do to nearby technology ie (cellphones laptops or their signals)

ok it worked thankyou if i were dealing with another folder would the file path just be longer ie if there was another folder in Python22 would it just be something like C:\Python22:/programs

done its there now what? exec myfirstprogram.py?

note: myfirstprogram.py is saved on the desktop and on the C:(there are two copies) drive under the folder Python22 C:\python22 dir C:\Documents and settings/owner>cd C:\python22 dir the system cannot find the path specified. C:\documents and settings \owner>

yeah that was command prompt-python (what i got after i typed python into the command prompt window) was i not supposed to type python into command prompt"?

C:\Python22 file "<stdin>", line 1 C:\Python22 ^

i don't understand much of what it says...so where does it say what I'm supposed to DO is it trying to say that i need a more complete file path or what? nowhere do I see a "click on this it will open the area where you type you're code" or a "remember to include this in your command" is there a cliff notes version of this? any difference between typing python.exe vs python?

does that mean that the moon is falling or does it mean that it is slowing the rotation of the earth?

yeah i did mean planets and perpetual thankyou for correcting the error. so do orbits decay until the object collides with what it is orbiting? ie. the moon will hit the earth and the earth will slowly spiral into the sun?

is radiation not a problem?

well i had an idea to try to build a electromagnet and i was woried that it might disrupt nearby electronics (would it damage anything at close range? such as >5 feet) and how would you make an electromagnet big enough to pick up small metal components from 8-10 yards? how close close can an electronic device be before it is damaged by a magnetic field of this strength?

ok i found the command prompt and entered the command python.exe and the name of changed to comand prompt - python.exe so now what?

is a plaint (or anything else) in orbit perceptual motion?

i just added that part to make it obvious that it needs to be low temperature it can't glow red hot it has to be mostly light and little heat

that is right 3x^3*y^4 not 3x^3y^4

perhaps a miscellaneous forum for "scholarly" topics outside of science. like history,language mechanics, literature etc?

is there to mix some chemicals to make a chemical reaction that would make it glow (like bioluminescence or glow in the dark) and could this be added to paint in some way to make a surface that would be more visible in the dark?

sometimes i click the start menu and click on python(command line) that opens a window called python(command line) and sometimes i go to the C drive to click on the program and that oppens C:\python22\python.exe they both open identical windows except for the name(a small black window with white text in what appears to be python). i have the windows version http://wiki.python.org/moin/BeginnersGuide/Download

would activating a large electromagnet create an EMP? or if you just turned it on and off quickly would that be an EMP?

is the command prompt the same thing as a (command line) when i do that they close before i can see the output its still closing in before i can see if it works was this meant to be in quotes?in the actual code? now the program runs when clicked C:\python\python.exe myfirstprogram.py file "<stdin>', line 1 C:\python\python.exe myfirstprogram.py ^ SyntaxError: invalid syntax

i guess I this whole python is beyond me

python.exe myfirstprogram.py file '<stdin>",line 1 python.exe myfirstprogram.py _____________________^ syntaxerror: invalid syntax
