Question

can someone help me with my math homework?

Answer 1

Sure, post your question/s here!

Answer 2

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

Answer 3

Oh, to type that you must use this notation:

\ [ x^2 \ ] gives
\[ x^2 \]

Answer 4

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

Answer 5

thats complicated

Answer 6

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

Answer 7

Ok, I think you were trying to type this:

\[a^ma^n=a^{m+n} \]

if so, this is the "exponent addition law".

Answer 8

yes that is exactly what i was trying to type

Answer 9

whats the answer?

Answer 10

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.

Answer 11

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

Answer 12

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

Answer 13

ARGH, my error!

\[4^74^{12}=4^{7+12}=4^{19}\]

Four to the nineteenth power. = HUGE.

Answer 14

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

Answer 15

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

Answer 16

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?

Answer 17

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

Answer 18

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. :)

Answer 19

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

Answer 20

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!

Answer 21
