can someone help me with my math homework?

OpenStudy (mathteacher1729):

Sure, post your question/s here!

OpenStudy (anonymous):

aman=am+n thats the first problem...... the m and ns go on top

OpenStudy (mathteacher1729):

Oh, to type that you must use this notation: \ [ x^2 \ ] gives \[ x^2 \]

OpenStudy (mathteacher1729):

Or click the "equation" button on the left of the text input field, and type your equation. :)

OpenStudy (anonymous):

thats complicated

when i see math i get lost.... is there any other way you could help me?

OpenStudy (mathteacher1729):

Ok, I think you were trying to type this: \[a^ma^n=a^{m+n} \] if so, this is the "exponent addition law".

OpenStudy (anonymous):

yes that is exactly what i was trying to type

OpenStudy (anonymous):

whats the answer?

OpenStudy (mathteacher1729):

There isn't any "answer", really. It's stating a rule. :) a = "the base" m, n = "the exponents" The rule says that if you (LEFT SIDE) multiply two numbers together, if the bases are the same, you (RIGHT SIDE) add the exponents and keep the base the same.

OpenStudy (anonymous):

ok im lost... how would you do it though?

OpenStudy (mathteacher1729):

So they might ask you something like: \[ 4^74^{12}=??\] and you would say ... \[4^74^{12}=4^{7+12} =4^19\] Which, by the way. Is A HUGE NUMBER. :-p

OpenStudy (mathteacher1729):

ARGH, my error! \[4^74^{12}=4^{7+12}=4^{19}\] Four to the nineteenth power. = HUGE.

OpenStudy (anonymous):

im confused.... is there any way you could teach it step by step?

OpenStudy (anonymous):

where do you get numbers if there is only letters??

OpenStudy (mathteacher1729):

I just made up the "bases" and the "exponents" then followd the followed the rules. It sounds like you need a quick refresher on exponents. Have you heard of Khanacademy?

OpenStudy (anonymous):

no i havent.... i have a math class tonight but i never understand it

OpenStudy (mathteacher1729):

Ah, ok. I would recommend starting by going to http://www.mathtv.com and then clicking Algebra ==> Exponents ==> Definitions and Properties Watch the first two videos. That guys is a GENIUS who explains things VERY WELL. :)

OpenStudy (anonymous):

ok thank you... ill try to see if i finally get it

OpenStudy (mathteacher1729):

Yeah, that guy is the best. I think you may find his vids helpful. Khanacademy is another free video service, but he's not as organized as Mathtv. :) Best of luck to you!
