I know that... I don't want anyone to give me the answer to my question I just need it to be explained to me because I don't know how to start the problem off..

- skullpatrol

OK I'll try if you do :-)

- anonymous

okay hold on. ill show you the problem.

- anonymous

What is the simplified form of
–9m–2n5 × 2m–3n–6

- anonymous

its actually like
-9m^ - 2n ^ 5 x 2m ^ -3 n ^ -6

Draw it please.

- skullpatrol

Much better, thank you :-)

- anonymous

No problem :) haha it can be confusing when typing equations :/

- skullpatrol

Do you know that when you multiply powers with the same base you add the exponents.

- anonymous

Yeah I do.

- PhoenixFire

\[-9m^{-2}n^52m^{-3}n^{-6}\]
You'd use the rule of:
\[ax^nbx^m=abx^{n+m}\]

- anonymous

I've never seen that rule before?

- anonymous

So the 5 and the 6 are going to be added??

- anonymous

-6*

- skullpatrol

Yes.

- anonymous

- anonymous

Is this right?

- skullpatrol

Not completely.

- anonymous

where is it wrong?

- PhoenixFire

Add the powers up again. (-2)+(-3) and (5)+(-6)

- anonymous

would that be-5 & -11?

- anonymous

yayy! ok hold on im gonna try and work it :)

- anonymous

|dw:1359749280221:dw|

- skullpatrol

$$5 + (-6) =?$$

- anonymous

-1

- skullpatrol

Correct.

- anonymous

ohh alright. but is that the answer? I thought it would get turned into a fraction?

- skullpatrol

We are not finished.

- anonymous

what's the next step? I don't know it.

- skullpatrol

First fill in the correct exponents please.

- anonymous

|dw:1359749569881:dw|

- skullpatrol

Good job. The next step is to put the factors with the negative exponents into the denominator of a fraction.

- anonymous

- anonymous

like this?

- skullpatrol

Correct. Excellent work!
